The AS1716 capacitive-sensor-interface IC interfaces piezoelectronic capacitive sensors and finds use in automotive knock sensors. The device provides differential inputs; differential-to-single-ended ...

LONDON — ZMD AG (Dresden, Germany), a global supplier of analog and mixed-signal solutions for automotive, industrial, and medical applications, has expanded its family of capacitive sensor signal ...

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 displacement sensors span a wide range of resolution, from the touchscreen sensors which can only detect displacement as a binary state, all the way to the sensors in semiconductor fabs ...

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 ...

When it comes to touchpads, most OEMs buy complete subassemblies from outside vendors, essentially subcontracting the electronic design as well as the assembly. The AD7142 capacitance-to-digital ...

Creating capacitive touch-sensitive buttons is easy these days; many microcontrollers have cap-sense hardware built-in. This will work for simple on/off control, but what if you want a linear, ...

The U.S. Patent and Trademark Office on Tuesday issued Apple a patent for a touch pad that removes the traditional "clickable" integrated button, replacing it with four or more force sensors and an ...
