Figure 2 Force Sensing Resistor with Pull Down Resistor. Adafruit Industries, Unique & fun DIY electronics and kits Round Force-Sensitive Resistor (FSR) [Interlink 402] ID: 166 - FSRs are sensors that allow you to detect physical pressure, squeezing and weight. However, they have been proved to be hysteresis prone and offer nonrepeatable readings due to their highly voltage-dependent electrical resistance. As their name implies, force sensing resistors use the electrical property of resistance to measure the force (or pressure) applied to a sensor. Force range: 0 to 20 lb. We brought the first FSRs to market 35 years ago. The force sensing resistor is generally supplied as a polymer sheet or ink which is applied as screen printing. The “force sensing resistor” or FSR is not an ideal term, since it is actually sensing the pressure and the output is dependent on the pressure on the surface of the resistor.

How force sensitive resistor can measure pressure/force. The harder the force, the lower the resistance. Force Sensing Resistors, commonly known as FSRs, were created back in 1977 with the sole purpose of making electronic musical instruments more expressive.What started out as a product created for strictly one industry has skyrocketed, opening up thousands of different application opportunities in the process. This is a force sensitive resistor with a square, 1.75x1.5", sensing area. This force-sensing resistor (FSR) from Interlink Electronics is a passive component that acts as a variable resistor, with resistance decreasing in response to increasing applied force, which makes it easy to add a touch interface to your project or create a robot with much more sophisticated tactile senses than are possible with simple lever switches.
