Capacitive sensing is a contactless-sensing technique with numerous applications, ranging from proximity sensing (Fig. 1), gesture recognition, automotive rain sensors, and remote liquid-level sensing ...

In the past, capacitive sensors for automotive electronics were rarely used, as they were deemed to be hard to control, difficult to read out, sensitive to aging, and temperature dependent. On the ...

Most proximity sensors use an electromagnetic field to sense the presence of a target metal. But there are times when it's necessary to sense nonmetallic materials such as plastics, liquids, or ...

A Capacitance Measurement System for the inspection of fastener hole quality has been used by numerous aerospace manufacturers and end users for over a decade. The two new sensors discussed in this ...

The introduction of micropatterns is an effective strategy in enhancing the sensitivity of capacitive pressure sensors. Towards this goal, scientist in China developed a novel approach for ...

When you look at switching solutions for electronic wearables, your options are limited. With a clever application of conductive fabric and thread, you can cobble together a simple switch, but the ...

Hundreds of millions of micromachined, piezoresistive Manifold Absolute Pressure (MAP) sensors have been produced to reduce pollution and improve fuel efficiency in engine control systems. Other ...
