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-touch sensors can detect a finger touch by measuring capacitive changes on the touch pad. Currently, the most popular form of capacitive-touch sensors relies on a microprocessor and ...

Here he’s created three touch sensors, connecting them to the Teensy microcontroller with two resistors each. The larger resistor (looks like 4.7 megaohms here) sends a signal through the copper ...

iPHONE owners have noticed a recent change in their smartphones' behaviour, with Apple devices requesting users unlock with a passcode or four-digit PIN rather than the Touch ID fingerprint sensor.

Apple engineers, too, are imagining ways to put the Touch ID fingerprint sensor on the Apple Watch. At least according to a patent application, that is.

The touch sensors, the shield, and the guard sensor are all controlled by the PSoC. This microcontroller is also configured in firmware to drive a set of LEDs that indicate when a finger touch occurs.

Apple’s new iPad Air has a fingerprint sensor in the power button. It’s a convenient location that would make a lot of sense for the upcoming iPhone 12, too.

For instance, if the earbud can detect a touch, it may also be able to detect movement. So changing the volume on a pair of AirPods might be done by simply swiping across the surface of one.
