FSR Sensor Overview

The Trigno 4-channel FSR (Force Sensitive Resistor) Sensor is an ac-
cessory to the Trigno EMG System designed to provide relative pres-
sure information of body-contact surfaces, such as the heel, the toe
and the fingers. Each sensor transmits 4 independent analog signals,
each servicing an individual FSR membrane. Three FSR membrane
sizes are available for optimizing performance in varieties of scenarios.
One 4-channel FSR Sensor occupies one position of the 16 possible
sensors in a Trigno network. Data are expressed as a percentage of the
sensor's full scale limits. These devices are useful for identifying the
timing of significant events and for making relative amplitude com-
parisons, but are not suitable for making absolute measurements of
force or pressure.
