Capacitive sensor interfaces are critical to the accurate measurement of physical parameters such as pressure, humidity, and force across a broad range of applications including biomedical devices, ...

Capacitive sensing provides a robust alternative to traditional mechanical switches. However, some applications cannot accommodate the physical implementation of a printed circuit board directly under ...

Depending upon the distance between the surface of a capacitance probe and a target source, the electrical capacitance that is formed between these two objects will vary. In an effort to improve ...

Abstract: In this paper present two type capacitive sensors with coplanar electrodes for core clamping system power accumulators. The sensor measures the compression ratio of the stator core as the ...

Given the extremely small capacitance changes measured, it is no surprise that noise can wreak havoc if allowed to couple in between electrode and IC. Noise can cause digital data corruption via ...

Two tiny ICs and a few passive components can yield a capacitive proximity sensor with excellent sensitivity and extremely fast response time. The circuit’s operation leverages the pulse-front-edge ...

A finger-heating effect has been observed on mutual capacitive touch sensors with plastic film overlay. The symptom is exhibited as serious sensitivity degradation when there is a greater than 10°C ...
