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 ...

You can’t have a touch sensitive switch without a way to detect the presence of a finger! A touch sensor, especially a capacitive touch sensor, has some surprisingly sophisticated electronics to ...

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, ...

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 ...

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 ...

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 ...
