You can find capacitive sensors in a soft-touch wall switch, a laptop sensepad, a washroom faucet hand sensor, a digital construction level, an airbag accelerometer, or in a super-accurate laser positioner. Or nearly anywhere else, in both discrete and silicon implementations.

THE BOOK

Very important for a complete understanding. Capacitive Sensors, Larry K. Baxter, IEEE Press, NJ 1997, ~300pp, is a  tour-de-force treatment of this complicated subject, with intense theoretical background, yet it is complete with many practical designs, including schematics and performance data. It's hard to understate the value of this blockbuster. Authored by the proprietor of this website, Capacitive Sensors can be purchased from www.amazon.com or contact the proprietor directly.
