FlexiForce Pressure Sensor - 25lbs.

This is a piezoresistive 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.

This sensor comes in three flavors. This sensor ranges from 0 to 25lbs of pressure.

Core Skill: Electrical Prototyping

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.

Customer Comments

  • What is the difference between a pressure sensor and a force sensing resistor like this one?

  • Hey all, I made a guide on setting this up and calibrating it with an op amp and Arduino. The data is accurate, and it gives about 12 gram resolution on this sensor. Seraphdrone.com/blog/flexiforce-pressure-sensor-with-arduino

  • I would really like to order this sensor. Any idea when this will be back in stock?

  • Anyone know how precise these things are?
    I have an object that is 5 lbs but can go up to 7 lbs. I would like to know the difference in at least 1 oz increments. Can this do it?

Good product

Does what it says on the label. Easy to use and set up, worked perfectly for my semester-long project.
