Trigno Snap Lead Sensor

Supporting traditional EMG research

The Trigno™ Snap Lead Sensor can connect to industry-standard pinch electrodes, for a more “traditional” approach to sEMG detection. The sensor’s flexible clamp leads allow users to adjust their inter-electrode spacing as they deem suitable, and also enable data collection from difficult muscle sites.
