Hardware Specifications

The BIOPAC EMG100C device records activity from large and small muscle groups, including facial EMG for analyzing emotional responses. Facial electromyography (fEMG) typically uses surface EMG electrodes to detect activity at the zygomaticus (cheek), orbicularis oculi (around the eye), and/or corrigator (brow).

The BIOPAC EMG100C is compatible with the iMotions ECG / EMG Module.

Powerful software

for powerful research

The iMotions EMG Module integrates multiple EMG devices from BIOPAC and Shimmer for flexible data collection options. For example, with iMotions you can monitor EMG from several muscle groups around the body at the same time, or open up even more possibilities by pairing with the iMotions API or other biosensors. The flexible software connects, records, and live visualizes data, and is a complete experimental suite for EMG.
