Trigno™ 4-Channel FSR Adapter

Designed to provide relative pressure information of body-contact surfaces

Quote Request

The Trigno™ 4-channel FSR (Force Sensitive Resistor) Sensor is an accessory to the Trigno EMG System designed to provide relative pressure information of body-contact surfaces. Each sensor transmits 4 independent analog signals, each servicing an individual FSR 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. Several sizes ranging from 0.2″ diameter up to 1.5″ squares are available and can be interchangeably connected o the 4-channel wireless sensor. 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 comparisons, but are not suitable for making absolute measurements of force or pressure.

The Trigno™ Wireless EMG Systems are battery-powered biofeedback devices that enable researchers and clinicians to acquire EMG and related signals from subjects for biofeedback purposes. They are intended for relaxation training and muscle reeducation. Interpretation of the EMG and supporting signals by a qualified individual is required.
