Low price Custom high quality Thin Film Pressure Sensor Force Sensing Resistor FSR
♦ What is Force Sensing Resistor (FSR)?
Force sensing resistor or we call force sensor, can be defined as a special type of resistor which exhibits a decrease in
resistance with an increase in the force applied to the active sensing surface. The force sensing resistor is generally supplied
as a polymer sheet or ink which is applied as screen printing. Both the electrically conducting and non-conducting particles are
present on this sensing film. If force is applied to a surface of sensing film, then the particles touches the conducting
electrodes and thus resistance of the film changes. There are several resistive based sensors but force sensing resistors operate
satisfactorily in difficult environments and also requires a simple interface compared to other resistive based sensors.
Even though there are various types of force sensors, the force sensing resistors are having several advantages such as thin size
(less than 0.5mm), very low cost and also good shock resistance. The only disadvantage of FSR sensors is low precision, there will
be approximately 10% or more difference in measurement results. So it can’t be used as weighing equipment. It acts as a reaction
of force rather than as an accurate reading of pressure.
♦Applications of Force Sensing Resistor
There are numerous applications for force sensing resistors in various fields such as motion analysis systems, automobiles like
car sensors, resistive touch-pads, musical instruments, Medical bed, Measurement of bite force of teeth, die pressure
measurement,and so on. It may be used wherever pressure measurements and data collection are required.

This FSR is specifically designed to test the degree of bending of the sensor, the degree of bending, and the
size of the contact area has a great impact on the resistance change. Generally used for medical mattresses, seat cushions, game
gloves and other aspects.

Testing a FSR
The easiest way to determine how your FSR works is to connect a multimeter in resistance-measurement mode to the two tabs on your sensor and see how the resistance changes. Because the resistance changes a lot, a auto-ranging meter works well here. Otherwise,just make sure you try different ranges, between 1 Mohm and 100 ohm before giving up.
If you have force applied equipment, that is better, like below
How to connect FSR
FSRs are often a polyester with conductive material silk-screened on. That means they're plastic and the connection tab is crimped
on base polyester material. The best way to connect to these is to simply plug them into a breadboard.

use a clamp-style connector like alligator clips, or a female header.
a terminal block such as Phoenix #1881448
How to use FSR
Analog Voltage Reading Method
The easiest way to measure a resistive sensor is to connect one end to Power and the other to a pull-down resistor to ground. Then
the point between the fixed pulldown resistor and the variable FSR resistor is connected to the analog input of a microcontroller

The harder you press on the FSR, the brighter the LED will be! Remember, the LED must be connected to the PWM pin to work
