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 ...

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, ...

Adding pressure to a human-machine-interface (HMI) touch control can make it far more intuitive to use and allow it to recognize much more than simply “on” and “off.” With this new 3D information, a ...

(Nanowerk News) Researchers in Korea have developed a wearable and stretchable mutual capacitance touch sensor based on graphene electrodes that is capable of multitouch sensing as well as 3D sensing ...

Capacitive touch sensors have made homes i n scores of MP3 players and mobile phones. Of course, the mobile arena is no longer the only bastion for these devices. Today, sensor technology has ...

Before the introduction of the iPhone X and Face ID, Apple was considering ways to implement Touch ID on a smartphone without using an externally visible fingerprint reader, with one technique ...
