SEN-08685 Flexiforce Pressure Sensor - 100 lbs
SEN-08685 Flexiforce Pressure Sensor - 100 lbs
US$36.99
The harder you press, the lower the sensor's resistance. Pressing hard, 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.
