Tekscan A301 FlexiForce™ Piezoresistive Force Sensors

Tekscan A301 FlexiForce™ Piezoresistive Force Sensors are available off-the-shelf and are ideal for an easy proof of concept. The A301 sensors offer optimization for high-volume manufacturing and are suitable for embedding into products and applications. These components feature Enhanced Stability Series (ESS) pressure-sensitive ink for high-temperature and high-humidity environments. The Tekscan A301 FlexiForce™ Piezoresistive Force Sensors measure up to 4,448N (1,000lbs.). To measure higher forces, apply a lower drive voltage (-0.5V, -0.25V, etc.) and reduce the resistance of the feedback resistor (1kΩ minimum). For lower forces, apply a higher drive voltage and increase the resistance of the feedback resistor.
