Here is a great collection of touch switch circuits. A touch switch is an electronic device that enables us to control a circuit by simply touching a sensor. Simple touch switch circuit with 4011 – ...

The input impedance of the trigger is very high and the touch sensor switch can be triggered by the voltage induced in the human body. The relay is a 12 V DC relay operating at currents less than 200 ...

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 ...

The touchless touch sensor could provide a new level of sensitivity to human-like robotics. The past few years have seen significant progress in producing electronics that can bend, twist ...

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 ...
