Startup Somalytics Inc., spun out of CoMotion at the University of Washington, in November, will demonstrate two new products based on its miniature carbon-nanotube paper composite (CPC) capacitive ...

SEATTLE--(BUSINESS WIRE)--Seattle-based nanotechnology innovator Somalytics Inc. was named a finalist today in Fast Company’s 6th annual World Changing Ideas Awards in the On the Rise category. The ...

This application note shows how to use a PICmicro® microcontroller and minimal external circuitry to detect small capacitances. The design is based on an operational amplifier (op amp) integrator. A ...

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 ...

Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface and a microcontroller. This led [John Phillips] to ask why not embed such ...

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 ...

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 ...
