Force Sensitive Resistor - Small (0.16" Dot)

( Pololu )
SG$8.80


Force Sensing Resistors (FSRs) are robust, polymer thick film (PTF) devices that exhibit a decrease in resistance when increased pressure is applied to the surface of the sensor. This force sensitivity is optimized for use in human touch control of electronic devices such as automotive electronics, medical systems and industrial PCs. FSRs are not a load cell or strain gauge devices though they have many similar properties. They are more appropriate for qualitative rather than precision measurements. The harder the force, the lower the resistance. When no pressure is being applied to the FSR its resistance will be larger than 1MΩ. This FSR can sense applied force anywhere in the range of 100g-10kg.

Two pins extend from the bottom of the sensor with 0.1" pitch making it bread board friendly. There is a peel-and-stick rubber backing on the other side of the sensing area to mount the FSR.

This is force sensitive resistor has a sensing area of 0.16" diameter. This FSR will vary its resistance depending on how much pressure is being applied to the sensing area.
