Chemical and biochemical sensors have experienced tremendous growth in the past decade due to advances in material chemistry combined with the emergence of digital communication technologies and wireless sensor networks (WSNs) [1]. The emergence of wearable chemical and biochemical sensors is a relatively new concept that poses unique challenges to the field of wearable sensing. This is because...

The addition of sensors to wearable computers allows them to adapt their functions to more suit the activities and situation of their wearers. Here a wearable sensor badge is described constructed from (hard) electronic components, which can sense perambulatory activities for context-awareness. A wearable sensor jacket is described that uses advanced knitting techniques to form (soft) fabric st...

Wearable inertial sensors have become an inexpensive option to measure the movements and positions of a person. Other techniques that use environmental sensors such as ultrasound trackers or vision-based methods need full line of sight or a local setup, and it is complicated to access this data from a wearable computer’s perspective. However, a body-centric approach where sensor data is acquire...

Wearable sensors are the major part of Wireless Body Area Networks (WBANs) for provision of health care services and physical activity monitoring. In this paper, a brief survey of different types of wearable sensors presented along with sensor placement. Designing of wearable sensors for ECG and Blood pressure also discussed. Comparative study of FIR and IIR noise reduction ECG filters discusse...

OBJECTIVES As wearable sensors take the consumer market by storm, and medical device manufacturers move to make their devices wireless and appropriate for ambulatory use, this revolution brings with it some unintended consequences, which we aim to discuss in this paper. METHODS We discuss some important unintended consequences, both beneficial and unwanted, which relate to: modifications of b...

This paper addresses a wearable master device for physically handicapped persons whose arms are disabled. Optical fiber curvature sensors are used to measure the human body motion. For the developed wearable master device, a calibration and mapping method of the sensors is proposed to extract 2-DOF human shoulder motions. An experiment shows that the wearable master device can be used for a 2-D...
