1. What is a Capacitive Force Sensor?
A capacitive force sensor is a sophisticated electronic device that utilizes the principle of capacitance to measure force. It consists of two parallel plates separated by a dielectric material. When a force is applied, the distance between the plates changes, resulting in a change in capacitance. This change in capacitance is directly proportional to the applied force, allowing precise force measurement.
2. Working Principle
The working principle of a capacitive force sensor is based on the variation of capacitance. As an external force is applied, the distance between the plates changes, altering the capacitance. The sensor measures this change and converts it into an electrical signal, which can be further processed and analyzed. This enables accurate and real-time force measurements.
