What Is Force Sensing Resistor Technology

Force sensing resistor technology helps you measure force and pressure. People use these sensors in robots, cars, hospitals, and gadgets. The sensors use piezoresistive sensors to change force into electricity. SOUSHINE’s force sensing resistor technology is known for being accurate and tough. It is also easy to use in different products.

Piezoresistivity Principle

Piezoresistive sensors work by changing resistance when you push on them. This idea is called piezoresistivity. It is the reason force sensing resistor technology works.

Resistance Change Under Force

Here is how the piezoresistive effect works in these sensors:

• The piezoresistivity principle shows how resistance changes with force.
• Force sensing resistors are variable resistors. When you press them, resistance goes down.
• This lets you measure force very well.
• If you do not press, resistance stays high (Megaohms).
• If you press, resistance drops to lower numbers (Kiloohms).
• This happens because of the piezoresistive effect.

Continuous Force Measurement

Force sensing resistor technology lets you measure force all the time. You do not just get a yes or no answer. You see many numbers that show how much force you use. This makes force measurement systems more helpful and flexible. You can use these sensors in smart gadgets, medical tools, and controls. Piezoresistive sensors help you notice even small changes in pressure. This is important for measuring force exactly.

FSR Construction Overview

Force sensing resistors have many layers. Each layer has a job and a special material. SOUSHINE uses strong materials and smart designs. This makes their force sensing resistor technology last a long time and work well.

Material Response to Pressure

Conductive polymer materials react in different ways to pressure. How they respond affects how well you can measure force and pressure.

Sensitivity and Reliability

Conductive polymer composites act differently based on how many particles they have. If there are few particles, resistance drops as pressure goes up. This happens because electrons move between particles. If there are many particles, resistance rises with more pressure. This means the sensor works in a new way. SOUSHINE’s force sensing resistors can sense light touches as low as 0.2N and heavy weights over 100N. You get good pressure measurement for many needs.
