Abstract
This chapter presents an overview of the technology behind capacitive sensing in mobile devices and beyond. Capacitive-sensing systems handle signals from the pF range down to aF. Examples to illustrate this include “single-pixel” buttons, sliders, touch screens, and “kilo-pixel” fingerprint readers.
Challenges and solutions for sensors, architectures, algorithms, and circuit technology are discussed.
