Trigno 4-Channel FSR Adapter
Designed to provide relative pressure information of body-contact surfaces
Each sensor transmits 4 independent analog signals, each servicing an individual FSR (Force Sensitive Resistor) membrane. These thin membranes are often affixed to shoe inserts for recording foot pressure timing at the heel, the toe, the first and the fifth metatarsals. Alternatively, these same sensors can be used to assess grip force during grasping tasks, or pressure distribution on the back while seated or lying down.
