Operational principles & types of
capacitive touch sensors
Contents of chapter 2
2.1 Self and mutual capacitive touch sensors
First, you’ll learn the basics of how a touch detection system is implementing in systems with capacitive touch sensors. Then, you’ll get to know the operating principles of both self and mutual capacitive touch sensors.
2.2 Capacitive touch sensor applications
There are two main types of capacitive touch sensors: one and two dimensional touch sensors. You’ll get to know them both in this chapter, with the help of examples and their pros and cons.
