Here are some of our most commonly asked questions about force sensing resistors.
How do FSRs work?As pressure is applied, the resistance lowers and returns to its original value as the pressure is removed.
What is the difference between ShuntMode and ThruMode FSRs?
ShuntMode can detect a broader range of forces with a more linear output. ThruMode FSRs are more receptive to lighter forces.
What applications are FSRs typically used for?
They can be used for any application where force needs to be measured. Typical applications include Podiatry, Up/Down and Force/Speed Controls, Musical Instrument Controllers, Infusion Pumps, Motor/Tool Speed Control, Robotic Fingertips, Seat/Bed Occupancy Detection, and Inventory Control.
Did you know? FSR's are one of the most secure and intelligent ways pharmacies and other health professional buildings control medication inventory. Once the medication moves from the shelf, a notification can alert the manager. Read more about how other uses for FSR's in healthcare here.
What constructions can FSRs be designed as?
BTI can design your FSR with a Matrix Array, Single-Zone, Discrete Array, XYZ Pad, or Force Sensing Linear Potentiometer. These are all things our team of experienced engineers can explain to you and help decide which would work best for your application.
What is the typical lifecycle of an FSR?
FSRs can typically withstand 1,000,000+ actuations in their lifecycle.
What is the typical size of an FSR?
The size and shape are limited only by fabrication equipment and raw material sizes. BTI can produce FSR sizes of 31” x 47” approximately.
Who invented the FSR?
Franklin Eventoff invented the force sensor to create a musical children's toy. To learn more about the FSR invention story, read the full blog here.
