Continuous health monitoring using wireless body area networks of implantable and wearable medical devices is envisioned as a transformative approach to healthcare. Rapid advances in biomedical sensors, low-power electronics, and wireless communications have brought this vision to the verge of reality. However, key challenges still remain to be addressed. This paper surveys the current state-of-the-art...
Nowadays, the majority of the monitoring devices used in clinical settings is limited to specific applications and powered by highly specialized microcontrollers and pre-programmed DSP systems. Moreover, these kind of devices are usually connected to a high capacity battery to operate in case of power blackout. Nevertheless, considering that all the measured bio-signals depends from an amperometric...
The advent of state-of-the-art telecommunication devices like smartphones has led to a considerable increase in the amount of electronic communication exchanged. While the improved availability increases personal flexibility—reducing rigidity in time and place of communication—it comes at a price. The ‘anytime, anyplace’-accessibility, which has become the norm in today's (working) society, can cause...
The ability to detect and distinguish interactions in the workplace can shed light over productivity, team work and on employees' use of space. Questionnaires and direct observations have often been used as mechanisms to identify office based interactions, however, these are either very time consuming, yield coarse grained information or do not scale to large numbers of people. Technology has been...
Wearable technologies are changing the way we deal with health and fitness in our daily life. Nevertheless, while MEMS-enabled inertial sensors have conquered the consumer market, physiological monitoring has still to face barriers due to the complexity and costs of physical interfaces (e.g. electrodes), the degree of intuitiveness of the interaction and the processing required to reach satisfying...
In this paper, we explore the feasibility of developing a sensor-driven rehabilitation game for people suffering from dysphagia. This study utilizes the skin-like electronics for unobtrusive, comfortable, continuous recording of surface electromyograms (EMG) during swallowing and use them for driving game-based, user-controlled feedback. The experimental study includes the development and evaluation...
Social interactions have been traditionally studied via questionnaires and participant observations, imposing high burden, low scalability and precision. The goal of my research is to explore novel techniques to detect and monitor social interactions in indoor settings. Through the development of a scalable research platform it would be possible to study social dynamics at a finer granularity. The...
The requirements for wearables and portable medical devices present a number of challenges in terms of integration, autonomy and connectivity, and demand a careful co-design of hardware and software to reach optimum performance. This paper addresses these challenges by way of some recent examples of ASICs designed for ECG, EIT (Electrical Impedance Tomography) and PPG (Photoplethysmography) sensors...
Intra wireless body sensor network (Intra-WBSN) is typically a short range wireless health monitoring network, consists of wearable or implant bio-sensor nodes which collects the patient's physiological signals and forward to patient monitoring systems. Network lifetime maximization and energy efficiency of the network have significant attention for current research. Recently cost-function based multi-hop...
System aims to design and implementation of ATM based remote health care monitoring system. The drastic rise in ATM transaction costs which covers telecom, security, network, power management and cash management results in lower operational savings and pressurized profitability. This allows an individual to check the medical parameters such as Blood glucose level, Blood pressure, Heart beat, Body...
Consistent cost effective health monitoring has become the need of the hour especially for the unstable, chronically and critically ill. Here we present a novel architecture and algorithmic methodology combining the sensing subsystem and the analytics engines. Physiological parameters from multiple sensors feed into a severity quantizer and a subsequent multiplexer, the output of which is processed...
A photoplethysmogram (PPG) is a plethysmogram which is optically obtained, a volumetric measurement of an organ. Two PPG signals are used here to estimate the blood pressure and heart rate. Blood pressure is the pressure exerted by circulating blood upon the walls of blood vessels. Nowadays the standard blood pressure is measured by using cuff based digital devices. In cuff based method, there will...
Medicines are the primitive solution for the prevention and cure for most of the diseases. Many risky diseases can be cured and prevented with the use of proper medication. The main objective of our proposed system, is to ensure a user friendly design that the patients can use as a reminder alert to take their daily medications on time. A wearable device is designed which is used to monitor the heartrate...
Health data is one of the most sensitive data available and its misuse can very easily endanger human lives. Ergo, each system and process in Body Sensor Network (BSN) which accesses this data needs to be secured well enough. In order to achieve this high security along with low energy consumption, a key management scheme named as Double Encryption has been proposed here. The proposed method uses...
Falling, which will cause serious physiological and psychological injuries, is a common health problem for senior people all around the world. Currently, with the increasing demands for fall detection and prevention, a large numbers of systems are developed and tested using different technologies. For all-time prevention of falls in daily life, an experimental study on a novel fall prevention system...
Body weight is an important measurement parameter towards management of obesity, diabetes and overall health. Previous research and society at large has primarily focused on long-term fluctuation in body weight to describe and quantify weight gain or loss. Meanwhile, little emphasis has been placed on the potential benefit of monitoring short-term body weight changes. Activities of daily living including...
There is a growing interest in the use of smartwatches to collect real-time physical activity and health care data. Much of this information is useful only when the person is wearing the smartwatch. Collecting data during other times consumes precious battery life and potentially communication bandwidth to relay the information. An approach that can correctly classify temporal regions during which...
The paper presents the laboratory based model of an “Energy Management Unit” for the optimum use of the electricity produced from alternative sources like biogas plant and solar photovoltaic system at an agriculture farm. The electrical energy produced at the farm is distributed among the loads according to the availability and requirement. A diesel generator is used as a backup at the farm. If the...
Smart health service means utilizing the integration and collaboration of Internet of Things technology and modern health service technology to realize smart health service featuring ubiquity and personification. In consideration of the requirement and objective of health service and based on the 3S system of Internet of Things, this paper attempts to study and establish a user-centered, health service-driven...
Today, we find many children with difficulties in dealing with physical and mental tasks. Technology promotes welfare of the differently abled children along with bringing social justice to them on humanitarian grounds. Assistive devices with sensor technology are the humanitarian technologies which are essentially required for the differently abled children. They can have a better life if they are...
