Transparent and flexible graphene-based touch sensor. (a) Schematic diagram illustrating the concept of a graphene-based capacitive sensor. The sensor consists of three layers. The top and bottom ...

A simple four-component circuit allows a single I/O line from any microcontroller to sense the states of two capacitive touch sensors. With so many cell phones, PDAs, and MP3 players using touch ...

The EH570 is currently the world’s smallest rectangle shaped fingerprint touch sensor in EgisTec’s lineup. The sensor can be integrated as either a home or side button of a smartphone.
