  2. Touchscreen - Wikipedia

    en.wikipedia.org/wiki/Touchscreen

    Back side of a Multitouch Globe, based on projected capacitive touch (PCT) technology Schema of projected-capacitive touchscreen. Projected capacitive touch (PCT; also PCAP) technology is a variant of capacitive touch technology but where sensitivity to touch, accuracy, resolution and speed of touch have been greatly improved by the use of a ...

  3. Capacitive sensing - Wikipedia

    en.wikipedia.org/wiki/Capacitive_sensing

    Capacitive sensors are constructed from many different media, such as copper, indium tin oxide (ITO) and printed ink. Copper capacitive sensors can be implemented on standard FR4 PCBs as well as on flexible material. ITO allows the capacitive sensor to be up to 90% transparent (for one layer solutions, such as touch phone screens).

    en.wikipedia.org/wiki/Visual_Planet

    Projected capacitance is used to allow interactivity through any non-metallic surface and involves the relationship between a conductive pad and a third object. In touch screen applications, the third object can be a human finger. Capacitance forms between the user's fingers and the wires in the conductive pad.

    en.wikipedia.org/wiki/Multi-touch

    Multi-touch is commonly implemented using capacitive sensing technology in mobile devices and smart devices. A capacitive touchscreen typically consists of a capacitive touch sensor, application-specific integrated circuit (ASIC) controller and digital signal processor (DSP) fabricated from CMOS (complementary metal–oxide–semiconductor ...

    Video demonstrating the operation of a touch-sensitive lamp A touch-sensitive lamp is a combination of a lamp and a touch switch. They act on the principle of body capacitance, activated by human touch rather than a flip, push-button, or other mechanical switch. They are popular as desk and nightstand lamps. Touch-sensitive lamp switches may be ...
