What is FSR in electronics?

What is FSR in electronics?

The Force Sensing Resistor (FSR) was invented by Interlink Electronics and first brought to market in 1985. When force is applied to the sensor, its conductive substrate makes contact with printed circuit substrate, allowing electricity to flow from one wire to the other.

Is FSR linear?

Since the FSR resistance is roughly inversely proportional to applied force, the end result is a direct proportionality between force and voltage; in other words, this circuit gives roughly linear increases in output voltage for increases in applied force.

How does an FSR work?

A force sensitive resistor (FSR) is a material which changes its resistance when a force or pressure is applied. Conductive film is an example of such force resistance material. In other words, force sensitive resistor it’s a sensor that allow you to detect physical pressure, squeezing and weight.

How do you use a force sensing resistor?

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 such as an Arduino (shown).

What is FSR made of?

The FSR is made of 2 layers separated by a spacer. The more one presses, the more of those Active Element dots touch the semiconductor and that makes the resistance go down. FSRs are basically a resistor that changes its resistive value (in ohms Ω) depending on how much it is pressed.

What is the full form of FSR?

What are force sensors made of?

The sensor body is usually made of aluminum or stainless steel, which gives the sensor two important characteristics: (1) provides the sturdiness to withstand high loads and (2) has the elasticity to minimally deform and return to its original shape when the force is removed.

How do you make a FSR?

DIY Force Sensitive Resistor (FSR)

  1. Step 1: Materials. Tools. Soldering iron.
  2. Step 2: Sizing. Use the knife/razor to score your PCB into two plates that mirror each other.
  3. Step 3: Connecting the Pieces. Glue the three pieces together.
  4. Step 4: Test It Out. Grab a multimeter and measure the resistance across your FSR.

Is a resistor a sensor?

Force sensing resistors are a piezoresistive sensing technology. This means they are passive elements that function as a variable resistor in an electrical circuit.
