What Is an FSR Pressure Sensor?
An FSR (Force Sensing Resistor) is a sensor that converts applied mechanical force into a measurable electrical signal. Baoshengda’s thin film FSR sensors use semi-conductive materials with resistance decreasing under pressure, enabling tactile and force measurement in compact electronic structures.
FSR sensors are useful when the product needs pressure detection, relative force feedback or threshold sensing instead of only a simple on-off switch signal. The final response depends on the sensor structure, actuator, housing, adhesive, reading circuit and calibration method.

FAQ
What is the minimum detectable force?
It depends on the sensor design. Some designs can detect as low as 10g, and the response can be configured per application.
Can the FSR sensor be flexible?
Yes. The sensor can be designed as an ultra-thin flexible film, with thickness down to 0.1mm available based on project requirements, and can be suitable for curved surfaces.
Can multiple keys be integrated in one sensor?
Yes. Each key can have independent function and point array based on the customer’s functional layout and electronic interface.
Are the sensors waterproof?
They can be designed with a sealed structure. The final waterproof performance depends on the customer application, material selection, adhesive choice and assembly method.
What industries use FSR sensors?
Common applications include medical rehabilitation, smart wearables, automotive, industrial control and consumer electronics.
Can Baoshengda assist with design optimization?
Yes. Our engineers can review drawings, interface, point layout, environmental requirements and functional design before sampling.
