Trigno™
Wireless Systems

The Trigno™ Wireless EMG System is a high-performing device designed to make EMG signal detection reliable and easy. Each EMG sensor has a built-in triaxial accelerometer, a transmission range of 40 m and a rechargeable battery lasting up to 8 hours. The system is capable of streaming data to EMGworks® Acquisition and Analysis software, and of generating 16 EMG and 48 accelerometer analog channels for integration with motion capture and other 3rd party data acquisition systems. Full triggering features further expand the possibility for integration with additional measurement technologies.
