Flex

Load cells, flex sensors and related force‑sensing elements turn mechanical pressure, bending or vibration into measurable electrical signals. Straight‑bar and disc‑type load cells provide high‑resolution resistance changes for weight‑tracking or structural‑monitoring tasks, while S‑type designs accommodate off‑centre loads. Thin piezoresistive pressure pads and flexible flex strips give a compact way to detect touch, grip or joint movement, with resistance rising as the element bends. Large‑area piezo films generate voltage spikes from vibration or shock, useful for impact detection. SoftPot membrane potentiometers offer a linear resistance gradient across a long, flat strip, enabling precise position sensing. Most of these devices output a raw resistance or voltage that can be conditioned with simple amplifiers or ADC interfaces, making them straightforward to integrate into microcontroller‑based robotics, automation and interactive projects.
