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.
