Force Sensors

Definition

Force sensors are devices that measure the amount of force applied to an object, converting this force into an electrical signal for further processing. They play a critical role in haptic interfaces and telerobotics by providing feedback about interaction forces, which is essential for simulating touch and ensuring safe robot operations. By detecting these forces, systems can replicate tactile sensations and help navigate environments while avoiding collisions.
