  2. Touch switch - Wikipedia

    en.wikipedia.org/wiki/Touch_switch

    Touch switch. A touch switch is a type of switch that only has to be touched by an object to operate. It is used in many lamps and wall switches that have a metal exterior as well as on public computer terminals. A touchscreen includes an array of touch switches on a display. A touch switch is the simplest kind of tactile sensor.

  3. Capacitive sensing - Wikipedia

    en.wikipedia.org/wiki/Capacitive_sensing

    Capacitive sensing. In electrical engineering, capacitive sensing (sometimes capacitance sensing) is a technology, based on capacitive coupling, that can detect and measure anything that is conductive or has a dielectric constant different from air. Many types of sensors use capacitive sensing, including sensors to detect and measure proximity ...

  4. Multi-touch - Wikipedia

    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 ...

  5. Touchscreen - Wikipedia

    en.wikipedia.org/wiki/Touchscreen

    A user operating a touchscreen. Smart thermostat with touchscreen. A touchscreen (or touch screen) is a type of display that can detect touch input from a user. It consists of both an input device (a touch panel) and an output device (a visual display). The touch panel is typically layered on the top of the electronic visual display of a device.

  6. Touch-sensitive lamp - Wikipedia

    en.wikipedia.org/wiki/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 dimmable, allowing the brightness of the lamp to be ...

  7. Applications of capacitors - Wikipedia

    en.wikipedia.org/wiki/Applications_of_capacitors

    Capacitors are used as the sensor in condenser microphones, where one plate is moved by air pressure, relative to the fixed position of the other plate. Some accelerometers use microelectromechanical systems (MEMS) capacitors etched on a chip to measure the magnitude and direction of the acceleration vector.

  8. Tactile sensor - Wikipedia

    en.wikipedia.org/wiki/Tactile_sensor

    The SynTouch BioTac, [2] a multimodal tactile sensor modeled after the human fingertip. A tactile sensor is a device that measures information arising from physical interaction with its environment. Tactile sensors are generally modeled after the biological sense of cutaneous touch which is capable of detecting stimuli resulting from mechanical ...

  9. Force Touch - Wikipedia

    en.wikipedia.org/wiki/Force_Touch

    Force Touch is a haptic pressure-sensing technology developed by Apple Inc. that enables trackpads and touchscreens to sense the amount of force being applied to their surfaces. Software that uses Force Touch can distinguish between various levels of force for user interaction purposes. [1][2] Force Touch was first unveiled on September 9, 2014 ...
