Wearable technologies can be innovative solutions for healthcare problems. Vis. This method is based on data. J. Electron. Part 15.4: Wireless Medium Access Control (MAC) and Physical Layer (PHY) Specifications for Low-Rate Wireless Personal Area Networks (WPANs), New York, USA (2006). smart cards, biometrics, optical character recognition systems, barcode systems, etc.) In [96] are used body worn microphones and accelerometers to measure acceleration and angular velocity through accelerometers and gyroscopes. Autom. This analysis can be done by means of sensors for force and inertia in the athlete’s footwear. The sensor use in the AAL/ELE platform is shown also in [107] and the position in the use-case scenarios is demonstrated in [108]. The recent advances in electronics and microelectronics allow the development of low-cost devices that are widely used by many people as monitoring tools for well-being or preventive purposes. Different types of gas sensors exist such as optical, surface acoustic wave (SAW), electrochemical, capacitive, catalytic, and semiconductor gas sensors. Many of the solutions to real problems related to human life are increasingly dependent on the human activity recognition. Bio-Sens. In fact, 32, million people are taking three or more medications daily, with even more med-. They can be located directly on the body as well. The aging of the population is accompanied by increased occurrence and spread of chronic diseases, and hence a significant increase in healthcare costs. The sensors and monitoring systems can provide insight into behavior changes that might signal changes or deterioration of health status. Studies of MOS nanodimension structures (e.g. : Low-power micro gas sensor. Image Vis. selecting or developing reasoning algorithms, to derive activities from sensor data. Other types calculate and transform some parameters, as falling angle, vertical projection histogram etc., but their disadvantage is the false alarm rates. Current developments of Micro Electro Mechanical Systems (MEMS) technology and communications allowed for the advent of low-cost, low-power sensor nodes having multiple functions in a compact formfactor. According to the American, Heart Association (2007), 49% of Americans use prescription drugs. Health monitoring and fall detection using IoT advantages can improve the daily lifestyle of elderly people. Chem. In order to improve people’s lives, it is very important to reduce threats when people get older, such as detect and prevent falls. In recent years, the number of people with diabetes has increased. (eds.) Interaction of a charged probe will result in accumulation or depletion of carriers within the transistor structure, which can be electrically detected by observing a direct variation in conductance or related electrical property [16]. In: Lin, Y.L., Kyung, C.M., Yasuura, H., Liu, Y. One approach is the called Assisted Living Systems (ALS). Wearable sensors focus mainly on mobile computing. One approach for handling the data generated by the networks of sensors is to use a platform of dedicated servers for collecting and processing information originating from the sensors. The transmitter uses a microcontroller which detects the patient’s pulse and converts it to a voltage signal and then displayed. The publication of Wang et al. Furthermore, the expensive healthcare facilities are getting free to be used for intensive care patients as the preventive measures are getting at home. The AAL’s assume that the older adults are passive and weak by default and it is not true in all cases as some people desire to support monitoring. Typically, a WSN node contains one or more sensors attached, embedded microprocessor with limited computational ability and memory, transceiver unit, and power unit [26]. Such sensors might be very valu-, able for ensuring the safety of elderly, forgetful persons who live alone. This network architecture corresponds to the core of the IoT, that is to provide immediate access to information at any time and any place. The wireless character of the sensor networks greatly complicates detecting and avoiding of snooping on the data. Another important issue that should be taken into account is the location at which the temperature will be measured because it is different at the different locations. (eds.) The power unit consists of an energy source for supplying power to the mote. Beside the already described attachment techniques, the sensors can be also placed within the object’s environment as long as the position allows the tracking activity. Technologies that can track changes in activities and alert the care provider are: a smoke detector; flood detector; temperature sensor; gas detector; occupancy sensor for bed; occupancy sensor for the chair; a fall detector; hanging around the neck, on the wrist, or clinging to clothing; an epilepsy sensor located under the bed and more. The longer someone stays unassisted, the less chance he/she has to make a full recovery. The data is analysed by integrated algorithm and can be compared to other patient’s experiences or previous health status of the same patient. For many types of sports, the main thing is running, jumping and throwing. In the sensor fusion, two cases are possible. Smart Sensors and Sensing Technology, pp. Springer, Cham (2015). - Massachusetts Institute of Technology, Program in Media Arts & Sciences (1997), Zhang, Y., Yang, L.T., Chen, J.: RFID and Sensor Networks: Architectures, Protocols, Security, and Integrations. The measured gas speed is used for (1) identification of gases by determining gas properties such as gas concentration, which is related to the difference of sound propagation time, and for (2) determining the components or the molar weight of various gases in mixtures proceeding from thermodynamic considerations [12]. Thesis (M.S.) These systems monitor the physiological signs of the patients in real time, can assess some health-conditions and gives the feedback to the doctors. J. Biomech. Whether you have a few refrigerators or hundreds, no two facilities are identical, and customization is the key to ensuring your continuous monitoring system is where you need it, when you need it. Also, a software system should be designed with modules for data processing, data extraction, vital signs detection to support human activity recognition (Fig. In the last two decades networking has been well developed and widely spread as a solution to dealing with information of any kind. Sensor networks could help in such cases. For this purpose, after a pinch, usually on the fingertip, a certain amount (drop) of blood is delivered to a special test strip which is placed in the analyzer and within a few seconds the current blood glucose level is indicated. Rimminen, H., Lindström, J., Linnavuo, M., Sepponen, R.: Detection of falls among the elderly by a floor sensor using the electric near field. In the 2000s, a new approach based on sensors utilizing other sensors fixed to objects was development. Healthcare organizations like insurance companies need real-time, reliable, and accurate diagnostic results provided by sensor systems that can be monitored remotely, whether the patient is in a hospital, clinic, or at home. The aim is to help elderly people by making use of four technologies: sensors, networks, monitoring daily activities and environment visualizing. 47–62. Patients who use electrically powered wheelchairs can move freely. Holtzinger and others [44] assessed the wrist unit that is well received by users. Appl. Smart sensor is a device that samples signals taken from the physical environment and processes them with its built-in computing resources before passing them to a centralized sensor hub. The huge amount of generated data could be processed by using cloud services, i.e. It acquires immense importance in helping elderly people who live alone in their own homes and need care [44]. Vis. GCN Government Computer News (2008). Comput. The indirect measures involve physical parameters that need to be monitored, as changes in the lung volume and movement. In: 2nd International Conference on Bioinformatics and Biomedical Engineering, Shanghai, China (2008). The normal state for the human organism is considered as 95% to 100% blood oxygen level. Commun. Sens. Liu, X., Cheng, S., Liu, H., Hu, S., Zhang, D., Liu, H.N. The RFID tag is a microchip with programmed identification plus an antenna. selecting and using appropriate sensors to objects and environments. Malnourishment, independence and activity are becoming vital metrics when monitoring in patient’s illness. 511–536. Health monitoring and fall detection using IoT advantages can improve the daily lifestyle of elderly people. Gas sensors determine the concentration of gas in its neighborhood. : I-living: an open system architecture for assisted living. Accordingly, it is not necessary to design a separate hardware device in order to integrate the benefits of both technologies. Modern methods of testing include periodic tests in specialized laboratories or analysis of daily profiles (periodically over several hours), using a portable blood analyzer at home. IET Digital Library. The notion of controlling things such as rail cars, machines, pumps, pipelines with sensors and SCADA systems is well-known to the industrial world for a century. Healey, J., Logan, B.: Wearable Wellness Monitoring using ECG and Accelerometer Data (2005). The second one is based on sensor-based activity recognition using the newly developed sensor network systems for motion monitoring. Bioautomation. 6180, pp. The protocol stack for WSN integrates power with routing aspects. The idea is the same with HMS with wearable sensors, the difference comes in the fact that here the sensors which detect body temperature, blood pressure or a heartbeat rate are located on patient’s body with no wires. Hence, the IoT paradigm requires for networking and sensing capabilities. Smart Sensors and Systems, pp. Springer, Cham (2015). Springer, Heidelberg (2008). Example of system architecture for fall detection with wearable sensors. Actuators A. Lochner, C.M., Khan, Y., Pierre, A., Arias, A.C.: All-organic optoelectronic sensor for pulse oximetry.

Tzanova, S., Codreanu, N.: Training microsystems technologies in an european eLearning environment. The measurements for blood glucose involve the glucose amount in human blood which concentration is usually lower in the morning and increases after every meal. Sensor and Activity-Monitoring Systems Sensor and activity-monitoring systems can track activities of daily living of sen- iors and other at-risk individuals in their place of residence. : A comparative review of wireless sensor network mote technologies. Using the same type of sensor application, an analysis of the impacts experienced by the athlete can be made. Gas sensing methods can be split into two categories: based on variation of electrical properties and based on variation of other properties [3]. For practical sensor development, a hybrid integration of transducer circuits composed of printed transistors and a common read-out and signal processing chip might be employed. Ambient and Wearable Sensor Fusion for Activity Recognition in Healthcare Monitoring Systems These systems do not require the use of base station, as cameras which have to be installed on particular area. From them we get the necessary indicators about the position and movement of the test object at a given moment, the pulse, temperature, and so on. 319–328. Sensors, Yamazoe, N., Shimanoe, K.: Theory of power laws for semiconductor gas sensors. discuss with one another. Weinland, D., Ronfard, R., Boyer, E.: A survey of vision-based methods for action representation, segmentation and recognition. Contemporary technology advancements, including electronics, digital embedded systems, wireless communications, and signal processing, have made it possible to develop sensor nodes with sensing, control, data processing, and networking features. Human body structure extraction data from images, action recognition and tracking across frames [99], survey on the approaches based on the movement recognition as opposed to structured approaches [100], research focused on monitoring human movement using 2D or 3D models and the other recognition techniques [101] etc. It is managed through the Internet and collects the information in a passive way respecting the privacy of the older adults. Microchimica Acta. At any random moment, a tag reader can just read one tag in its locality and a tag must be read by one tag reader [32]. In any case, the quantification of the acoustic impedance of gases is remarkably troublesome, particularly in a process environment and consequently it is rarely used in practice. In this paper, a review of IoT based smart health monitoring systems is presented. Dense sensing-based activity recognition is predominantly driven by smart environment applications such as ambient assisted living. : A low-cost electromagnetic tagging technology for wireless identification, sensing, and tracking of objects. It is a wireless method for sending and receiving data for various identification applications. Gas sensors are a class of chemical sensors. Tags might be either active or passive.

Kolte, PG Coordinator, Dept of EnTC, MITCOE 2. : A novel conformal RFID-enabled module utilizing inkjet-printed antennas and carbon nanotubes for gas-detection applications. The electrical variation methods rely on the following substances as a sensing material: metal-oxide-semiconductor (MOS) stacks, polymers, moisture absorbing materials, and carbon nanotubes. Similar to telemetric monitoring systems for high-risk patients, relatively simple AAL systems can perform two main tasks: In order to track precisely the position of elderly people, a precise positioning sensor network should be developed in real time. : Noninvasive glucose monitoring using saliva nano-biosensor. Generally, the information acquired by the tag is further processed by a more complex computer equipment. 4217, pp. IEEE Antennas Wirel. These include programme monitoring data, behavioural and biological trends data and evaluation of programmes. Some systems are based on human skeleton, but their computational cost is not valuable for real time situations. Sensor and Activity-Monitoring Systems Sensor and activity-monitoring systems can track activities of daily living of sen-iors and other at-risk individuals in their place of residence. The sensors are divided according to their purpose – there are different types based on particular output signals, involving theoretical principles and defined by technical infrastructure. The focus of our work is on continuous monitoring of cardiac patients in hospital especially in ICU and in homes using healthcare monitoring system based on wireless sensor networks. Perception layer contains different medical and environmental sensors that are collecting data in real-time. The actions that follow are based on probabilistic or statistical classification. : Development of a low cost compact low profile phase array antenna for RFID applications. The combination of semiconductor and information technologies enabled the use of huge amounts of sensors to be deployed anywhere, not just where electronics and power infrastructure exists, but anywhere valuable information is gathered regarding variety of characteristics a given object or thing. Image Underst. However, the real implementations are still fragmented and isolated. The Rochester University [50] developed a prototype smart medical home, consisting of computers, infrared sensors, video cameras and biosensors. In: Cuenca, P., Orozco-Barbosa, L. The sensitive elements consist of small ceramic “pellets” with varying resistance depending on the existence of target gases. Xu, S., et al. It achieves various goals like decrease in cost and long hospital stays; and continuous and remote monitoring without experts’ attendance is possible. So, the faster help is very important in these cases [61]. Therefore, by the quantified acoustic impedance and speed of sound, the density of a gas could be found out. Ultrasonic based acoustic sensors are principally classified as (1) ultrasonic, (2) attenuation, and (3) acoustic impedance. The networks integrate motion sensors, cameras and switches that define the activity and visualize the environment. RFID has many advantages since it is cost and power efficient, withstands severe physical environments, permits concurrent identification, and does not require line-of-sight (LoS) for communication. The acquired sensor data is presented as time series of state changes. Another used wearable sensor are GPS sensors. Typical applications include poly-silicon nanowire-based DNA or protein sensors, cantilever-based DNA sensors, pH sensors based on Ion-Sensitive-FET, glucose sensors, temperature sensors, etc. : Sensors for wireless body area networks (Healthcare Technologies, 2017) (Chap. Wang, C.-Y., et al. Because of the advances in these technologies, MEMS sensors become cheaper, lighter and small enough to carry. Healey and others [54] presented a monitoring prototype system that can record, transmit and analyze permanent echocardiogram data. Systems based on object monitoring have the same disadvantage as ambient devices and must be installed in all necessary rooms in order to cover the required range. Nowadays the state-of-the-art sensors are capacitive sensitive strain sensors [84], which are compressible and piezoelectric. Methods Inf. A RFID system typically consists of 3 major components: (1) an application host, which provides the interface to encode and decode the ID data from data reader into a personal computer or a mainframe, (2) an RFID tag, which stores the identification information or code, and (3) a tag reader or tag integrator, which sends polling signals to an RFID transponder (transmitter-responder) or to a tag that should be identified [31]. The methods for respiration rate measurement can be divided into two types, the first one detects directly the airflow during the breathing, the second one measure indirectly responding to chest and its expansion and contraction. They are the basis of wireless sensor networks. ications typically being taken by those 65 years of age or older. In addition to the constantly available communication interface between the observer and the user, it is also possible to automatically detect falls as well as momentary observation of many vital parameters. They are able to give the difference between an emergency case and everyday movements, for example, can detect if the person is just laying down or there is a sudden change in the position, which means a fall. There is a great interaction between biomedical and sports applications. The properties of carbon nanotubes (CNTs) allow the development of high-sensitive gas sensors. In: 2010 IEEE Education Engineering Conference, EDUCON 2010, Madrid, Spain (2010). They can also be embedded in other devices as shoes, belts, watches, etc. Physiol. These can also be named as m-health … Deviations from these norms can, be important warning signs of emerging health problems and can enable care-, In addition to widely used fire, security, and home gas detectors, there are, other sensors that can monitor appliances to detect whether a household appli-, ance is turned on or off and can sometimes switch the appliance on and off for, the resident.
