We describe the use of textile sensors mounted in a garment sleeve to detect affective gestures. The ‘ Sensor Sleeve’ is part of a larger project to explore the role of affect in communications. Pressure activated, capacitive and elasto-resistive sensors are investigated and their relative merits reported on. An implemented application is outlined in which a cellphone receives messages derived ...

Self-Powered Gyroscope Angle Sensor A self-powered gyroscope angle sensor based on the resistive impedance matching effect of TENG is proposed by Chun Zhao, Mingchao Sun, Zhen Wen, and colleagues in article number 2100797. The relationship between voltage variation rotation ranging from 0° to 260° near-linear with ultra-high sensitivity 67.3 mV deg−1. Moreover, quantized LED pattern alarm funct...

Polychloro-para-xylylene (parylene-C) is a flexible and transparent polymer material which has excellent chemical stability and high biocompatibility. Here we demonstrate a polymer device based on single-component parylene-C with memory and temperature sensing functionalities. The device shows stable bipolar resistive switching behavior, remarkable storage window (>104), and low operation volta...

A low power MEMS based sensor along with the embedded power efficient signal conditioning unit (Microcontroller based), which can be used with any suitable sensor-network to detect and quantify variations in a particular gas concentration, has been reported in this paper. The power consumption of the MEMS gas sensor is ~ 70mW to 100mW depending upon its operating temperature (150-250°C) and tha...

Various kinds of biosensors were developed for the environmental control. Microbial sensor consisting immobilized yeasts and oxygen probe has been applied to estimation of 5-day BOD. The response time of BOD sensor was less than 20 mm and the minimum measurable BOD was 3 mg l-. Amperometric microbial sensor for ammonia was constructed with immobilized nitrifying bacteria and an oxyger probe. Th...

The conventional design of the heater in a silicon micro-hotplate employ a simple meandering resistive track to form a square element. We show that this heater structure produces an uneven thermal profile characterised by a central hot spot with a significant variation in temperature of some 50 8C across the plate at an average temperature of 500 8C. Four novel micro-heater designs are reported...

Magnetometer is essential for finding out orientation of any object using earth’s magnetic field. This is done by measurements of earth magnetic field along three perpendicular directions. In this design magneto resistive sensors are aligned in perpendicular directions are used for measuring the field. Sensor output voltages are digitized using ADC and send to DSP. Algorithms are implemented in...
