This is a?Piezo resistive force sensor?from Tekscan. 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. Used as a presence sensor (someone standing), weight sensor, pressure sensor (impact testing), etc.
The overall length is about 8.5″. Sensor comes with 0.1″spaced, reinforced, breadboard friendly connector.
Flexiforce Pressure sensor comes in three flavors. Flexiforce Pressuresensor ranges from 0 to 100lbs of pressure in the mega-ohm range.
Detect and measure a relative change in force or applied load
