Theory of capacitive sensing

• Capacitive sensors measure a change in capacitance (increase or decrease)

• Human body, hand or finger acts as a capacitor

• Proximity or touch by a human changes the capacitance of the system

• Capacitance changes are small

• Touch – 10 pico Farads

• Close proximity – 1 pico Farads

• Proximity – 50-100 femto Farads

• Charge transfer – measures capacitance by transferring charge from sense electrode to internal capacitor

• Inexpensive PCB pads to sense a touch or proximity event

• No mechanical parts

• Front panel materials – glass or polycarbonate

• Buttons protected from harsh environments

Self Capacitive Sensing

• Controller measures capacitance of the sense electrode relative to ground

• One connection for each touch switch

• Hand or finger adds capacitance to circuit

Front panel

PCB TX/RX

Self Capacitive Sensing

• One connection for each touch switch

Projected Capacitive Sensing

• Also called mutual capacitance

• Controller measures capacitance between two sense electrodes

• Two connections for each touch switch

• Hand or finger subtracts capacitance from circuit
