Force Sensing Resistors And Linear Potentiometers

Force‑sensing resistors are passive devices whose resistance drops as pressure increases on the active area, providing a simple analogue signal that can be read by any microcontroller or data‑acquisition system. Linear potentiometers work on the same principle but vary resistance along a strip, allowing both the magnitude and the position of a load to be measured. Both types integrate easily with standard wiring harnesses and require no external power, making them reliable building blocks for tactile switches, pressure pads, load‑monitoring mounts and interactive surfaces. Their compact form and straightforward electrical characteristics suit a wide range of robotics, automation and embedded projects where real‑time force feedback or touch detection is required.
