This study presented a wireless smart contact lens system that was composed of a reconfigurable capacitive sensor interface circuitry and wirelessly powered radio-frequency identification (RFID) addressable system for sensor control and data communication. In order to improve compliance and reduce user discomfort, a capacitive sensor was embedded on a soft contact lens of 200 μm thickness using...

This paper reports a micromachined capacitive pressure sensor intended for applications that require mechanical robustness. The device is constructed with two micromachined metal plates and an intermediate polymer layer that is soft enough to deform in a target pressure range. The plates are formed of micromachined stainless steel fabricated by batch-compatible micro-electro-discharge machining...

This study describes a novel floor sensor network being developed to provide a competitive and universal pressure mapping technology for a wide range of medical, research and security applications. The presented sensor network consists of 16 sensor elements distributed in a 4x4 sensor matrix. The sensor elements are made of a special dielectric electro-active polymer film being capable of capac...

Abstract Capacitive pressure sensors that consume less power with temperature sensitivity have undergone many design modifications, in order to improve the performance for meeting application needs of various fields. In this paper, micro-pressure capacitive sensor is improved by adding a novel double-cavity structure and gas hole. The feature can amplify amplitude upper diaphragm, hole alleviat...

Abstract This paper presented a systematic approach to electro-textile pressure sensors dependent on interdigitated capacitors (IDCs) printed fabric. In this study, we proposed highly sensitive, broad-range sensor based the combination of porous Ecoflex, carbon nanotubes (CNTs), and electrodes. Firstly, characterizations capacitor using silver ink Cotton Polyester fabric were completed by preci...

Low noise position measurement is fundamental for space inertial sensors, and at present the capacitive position sensor is widely employed for space inertial sensors. The design for the possible suppression of the front-end electric noises for a capacitive sensor is presented. A prototype capacitive sensor with 2×10−6pF/Hz1/2 at frequency above 0.04 Hz is achieved and further improvements are d...

We present a study investigating the electrochemical interface as a capacitive transducer for ultrasound sensor applications. The concept is demonstrated using a nanoporous Au layer as a sensing electrode. The sensing electrode was produced by dealloying of the Ag0.8Au0.2 bulk electrode yielding an Au layer with extremely high surface/volume ratio. This electrode configuration was tested agains...
