In electrical engineering, capacitive sensing is a technology, based on capacitive coupling, that takes human body capacitance as input. Capacitive sensors detect anything that is conductive or has a dielectric different from that of air.
Many types of sensors use capacitive sensing, including sensors to detect and measure proximity, position or displacement, humidity, fluid level, and acceleration. Human interface devices based on capacitive sensing, such as trackpads, can replace the computer mouse. Digital audio players, mobile phones, and tablet computers use capacitive sensing touchscreens as input devices. Capacitive sensors can also replace mechanical buttons.

Famous quotes containing the word sensing:
“Something was still there, that something that distinguishes an artist from a performer: the revealing of self. Here I be. Not for long, but here I be. In sensing her mortality, we sensed our own.”
—Studs Terkel (b. 1912)
