What is an FSR?
Force-sensitive resistors (FSRs) are sensors that respond to the force applied to their surface by changing their resistance. Due to their high sensitivity, they are very suitable for use in touch-sensitive gadgets, robots, medical devices, etc. Multi-sensing points and matrix designs can conveniently obtain surface pressure distribution data. FSRs have a very flexible design, and their size, shape, and force range can be customized and developed according to project requirements, thus having very high project adaptability.
Key Features of FSR
FSR Product Categories
Single Sencell FSR
The purpose of the single-sensor fsr is to detect the pressure or force at a single position. They are perfect for direct touch-sensitive applications. For example, pen tip pressure sensing for styluses, AR game console controllers, mechanical hand control, ultra-thin pressure switches, etc
Multiple Sencells FSR
The FSR of multi-sensor units integrates multiple single-point FSRS in a single FSR product through series or parallel connection, achieving dynamic measurement and comparison of forces at multiple measurement points simultaneously. Typical applications include: electronic Musical Instruments, adjustment of the tightness of wristbands, digital sports insoles, pressure calibration of strip molds, flatness calibration of rollers, etc
Matrix FSR
Matrix FSR is a force sensor composed of multiple rows and columns. Its main function is to measure the pressure distribution and dynamic change process within the working area, and it is also known as a pressure map. It can be applied to many fields such as gait analysis, tire balance measurement, 3D seat design, smart mattresses for medical staff, and mold flatness measurement.
