Force & Flex Sensors
Force-sensitive resistors (FSR), flex/bend sensors, strain gauges, load cells, and weight sensors including amplifiers (HX711, NAU7802).
Piezo Element
SKU: SF-SEN-10293 | Brand: SparkFun
A simple piezo element that can be used as both a sensor and a small audio transducer. When flexed or tapped, it generates a voltage that can be read by a microcontroller, making it ideal for knock and vibration detec...

Force Sensitive Resistor - Square
SKU: SF-SEN-09376 | Brand: SparkFun
This is a force sensitive resistor with a square, 1.75x1.5", sensing area. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area. The harder the force, the lower the res...
