What is a Capacitive Force Sensor?

A capacitive force sensor measures the force applied to a surface by detecting changes in capacitance between conductive plates. When pressure is applied, the distance between plates changes or the dielectric properties of the material vary, resulting in a measurable electrical signal.

Key Features

• High sensitivity to small forces and pressure changes

• Compact and flexible design suitable for embedded systems

• Fast response time for dynamic applications

• Durable and long-lasting with minimal mechanical wear

• Low power consumption, ideal for portable or wearable devices

Working Principle

1. Force Application: Pressure is applied to the sensor surface.

2. Capacitance Change: The distance between electrodes changes, or dielectric material compresses.

3. Signal Detection: The sensor measures capacitance variation, which correlates to the applied force.

4. Output Conversion: Electronics convert capacitance changes into voltage or digital output for controllers or microprocessors.

This allows precise force measurement with minimal mechanical components.
