Surface EMG sensing

Electrodes placed on the skin over a muscle detect the electrical activity generated during contraction, amplified and filtered into a usable signal.

Where it's used

Bio-electronics experiment kits
Maker and classroom kits that turn a human or animal bioelectrical signal into readable electronic data — Backyard Brains' SpikerBox neuron/muscle recorders, OpenBCI's EEG/EMG acquisition boards and Ultracortex headset, BITalino's modular biosignal board, and Advancer Technologies' Muscle Sensor EMG module — the electronics-and-signal-acquisition counterpart to the microbe- and DNA-based kit categories in this catalog.
