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 ...

Imagine that you have a great idea for a product that includes a plastic injection-molded case or a glass panel, and you would like to explore the possibility of replacing the mechanical buttons with ...

(Nanowerk News) As part of ongoing acoustic research at Binghamton University, State University at New York Distinguished Professor Ron Miles has created a workable sensor with the least possible ...

Capacitive touch technology has made tremendous inroads into a wide range of applications since its introduction to the market. Touch technology began with resistive touch screens used in the first ...

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 ...

Electromechanical switches are simple, cheap, and widely available (Fig. 1). However, they’re also plagued with a number of disadvantages, including wear with repeated use, and the potential for ...

This article provides an overview of capacitive touchscreen technology and describes the challenges inherent in implementing this technology in handheld devices. Ever since Apple launched the iPhone ...
