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.

This sensor retains all the performance specifications of the Trigno™ Sensor family; including low noise operation, full EMG bandwidth capture ability, and seamless integration with the Trigno™ Wireless Systems. Our patented, parallel bar detection approach ensures reliability, ease-of-use and consistency across all data collection protocols.
