SparkFun Flexiforce Pressure Sensor - 1lb. Flex / Force Accessories & Supplies Improved lock button designThis is a piezoresistive force sensor from Tekscan. The harder you press, the lower the sensors resistance. Pressing lightly, the resistance changes from infinite to ~300k. The sensor itself is thin and flexible, but the resistance does not change while being flexed. Resistance changes only when pressure is applied to the round area at the end of the sensor. Used as a presence sensor (someone standing), weight sensor, pressure sensor (impact testing),
