Trigno Mini Sensor

Bridging physiology and technology

The Trigno™ Mini is a wireless EMG sensor that is ideally suited for recording surface EMG on small and “difficult-to-isolate” muscles. With a sensing head that measures only 25 mm x 12 mm x 7 mm, the Trigno™ Mini Sensor can be used for a variety of small muscle applications, including physical therapy, rehabilitation sciences, sports science, ergonomics, and motor control.
