Force Sensor

Definition

A force sensor is a device that detects and measures the force applied to it, often converting this physical force into an electrical signal for analysis. These sensors are critical in applications where precise force measurement is required, such as in robotics, medical devices, and haptic feedback systems. They enable systems to respond accurately to interactions by providing real-time data on the forces involved.
