Characteristics of physical activity are indicative of one's mobility level, latent chronic diseases and aging process. Accelerometers have been widely accepted as useful and practical sensors for wearable devices to measure and assess physical activity. This paper reviews the development of wearable accelerometry-based motion detectors. The principle of accelerometry measurement, sensor proper...

Wearable devices are used to record several physiological signals, providing unobtrusive and continuous monitoring. The main challenge in these systems is to develop new recording sensors ideally envisioning non-contact solutions. In this work we propose a wearable fiber-optic based sensor which basis of operation relies on the electro-active effect. Two main biopotential sensing components wer...

We present a research platform for combined physiological signal acquisition and context-awareness. This platform seeks to be wearable, it has extended battery life, it offers enough computational power to run context-recognition algorithms and it is flexible so that a variable number of sensors can be added to it. So far the system is composed of a wearable physiological signal acquisition dev...

In recent years, owing to the significant applications of health monitoring, wearable electronic devices such as smart watches, smart glass and wearable cameras have been growing rapidly. Gas sensor is an important part of wearable electronic devices for detecting pollutant, toxic, and combustible gases. However, in order to apply to wearable electronic devices, the gas sensor needs flexible, t...

We present work to develop a wireless wearable sensor system for monitoring patients with Parkinson’s disease (PD) in their homes. For monitoring outside the laboratory, a wearable system must not only record data, but also efficiently process data on-board. This manuscript details the analysis of data collected using tethered wearable sensors. Optimal window length for feature extraction and f...

In the future, diagnostic devices will be able to monitor a patient's physiological or biochemical parameters continuously, under natural physiological conditions and in any environment through wearable biomedical sensors. Together with apps that capture and interpret data, and integrated enterprise and cloud data repositories, the networks of wearable devices and body area networks will consti...

With the rapid progress in nanotechnology and microengineering, point-of-care and personalised healthcare, based on wearable and implantable diagnostics, is becoming a reality. Enzymatic fuel cells (EFCs) hold great potential as a sustainable means to power such devices by using physiological fluids as the fuel. This review summarises the fundamental operation of EFCs and discusses the most rec...

In this paper, we introduce 3D motion rendering system based on a data glove. Our glove measures the movement of fingers by using flex sensors. Integrated FPGA gathers the data from sensors and performs pre-processing of the sensor data. The acquired data are forwarded to PC through Bluetooth communication and an application program displays the gesture. Keywords-Ueser Experience, Wearable Devi...

This paper explores automation in monitoring the well-being of senior adults. Namely, it introduces TwitterJacket, an automated activity and health monitoring solution through the use of wearable sensors and mobile devices. The system takes advantage of wearable electrocardiography (ECG) monitoring and accelerometer data to recognize user activity and publish on Twitter. In this paper, we discu...

The industrial Internet of Things (IoT) is aiming to interconnect humans, machines, materials, processes and services in a network. Wireless Sensor Network (WSN) comprises the less power consuming, light weight and effective Sensor Nodes (SNs) for higher network performance. Radio Frequency Identification (RFID) and sensor networks are both wireless technologies that provide limitless future po...
