Capacitive Touch Sensors

Capacitive Touch Sensors are sensors that detect touch or proximity by measuring changes in capacitance caused by a conductive object near or on a sensing electrode. They convert these capacitance variations into electrical signals that can be interpreted as touch events.

Within the broader Sensors category, capacitive touch sensors are commonly implemented as dedicated sensing devices or as controller solutions that manage signal acquisition and touch detection logic.

• Operating principle: Capacitive field disturbance and capacitance change measurement
• Touch interface types: Self-capacitance and mutual-capacitance sensing methods
• Key characteristics: Solid-state sensing with no mechanical actuation required
