2. 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 ...

   en.wikipedia.org/wiki/Tactile_sensor

   A PPS tactile sensor system (TactileHead []) designed to quantify the pressure distribution over the face and head. Useful to optimise the ergonomic design of headgear and eyewear. 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 ...

4. 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.

6. TI MSP430 - Wikipedia

   en.wikipedia.org/wiki/TI_MSP430

   The integrated capacitive touch sense I/O module offers several benefits to touch button and touch slider applications. The system does not require external components to create the self-oscillation (reducing bill of materials) and the capacitor (that defines the frequency of the self-oscillation) can be connected directly.

7. Capacitor - Wikipedia

   Some fingerprint sensors use capacitors. Additionally, a user can adjust the pitch of a theremin musical instrument by moving their hand since this changes the effective capacitance between the user's hand and the antenna. Changing the effective area of the plates Capacitive touch switches are now [when?] used on many consumer electronic products.
