Capacitive touch sensors are entirely in the domain of DIY, requiring little more than a carefully-chosen conductive surface ...

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 ...

Capacitive reactance (Xc) increases as capacitance decreases and continues to grow to the point where virtually all the voltage drop occurs across this now open element of the circuit. Any remaining ...

Capacitive proximity sensor block diagram Capacitive proximity sensors use two metal electrodes or plates to generate a high-frequency electrostatic field.

The Apple iPhone brought the benefits of integrated multi-sensor technology to the masses, and while the application of sensors and their associated algorithms has multiplied and changed the world ...

The superior capacitive sensors can't go under your screen yet, and ultrasonic technology is still relatively new and expensive. Thus the optical scanner saw a resurgence in popularity.

This means that the Touch ID sensor should be remarkably accurate for living creatures, but it also means that only a finger attached to a beating heart will be able to unlock it.

ETH Zurich has created a yarn whose capacitance varies significantly with the movement of the textile it is woven into. The researchers “integrated it into a pair of athletic leggings”, according to ...
