The BN-EMG2 wireless EMG amplifier records the electrical activity of muscles without cable constraints.

BioNomadix · Wireless electromyography

The BN-EMG2 wireless EMG amplifier records the electrical activity of muscles without cable constraints.

Full freedom of movement for the participant while maintaining laboratory-grade signal quality.

BN-EMG2 is an expansion module, not a standalone system

The BioNomadix transmitter and receiver alone do not record or store data. Measurement requires an MP200 data acquisition unit (or the older MP160/MP150) together with AcqKnowledge software.

The BN-EMG2 receiver plugs into a channel input on the MP200, and the recorded signal is added to a shared, synchronized timeline alongside other modules — both wired and wireless.

Key features

Wireless operation

No cable between transmitter and receiver — full freedom of movement for the participant during EMG signal recording.

5-500 Hz bandwidth

Hardware high-pass and low-pass filters matched to the muscle signal.

Compact, lightweight transmitter

Discreet size, secured with a dedicated strap — does not restrict movement or bother the participant.

SNR > 65 dB

A clean signal even during dynamic movement (sensitivity <1.5 µV rms).

Compatibility: MP200 (and older MP160/MP150) + AcqKnowledge

Where to place the electrodes

Click the points on the silhouette to see where EMG activity can be measured for the selected muscles.

Locations are based on the publicly available SENIAM project recommendations (Hermens et al., European Recommendations for Surface EMG, 1999) — for illustrative purposes, without reproducing the original diagrams. Each point marks a measurement site — in practice this means an electrode pair (bipolar) per muscle, plus one shared reference/ground electrode placed on an electrically neutral bony landmark (e.g. wrist, elbow) — required in every EMG setup.

How it works

Transmitter on the participant

Secured with a strap or shirt, it records the EMG signal wirelessly.

Receiver + MP200

Transmission at 2000 Hz to the data acquisition system.

Analysis in AcqKnowledge

Automatic signal integration, frequency-domain analysis (mean/median frequency, power spectrum).

Experimental applications

Electromyographic measurements are a non-invasive gold standard in biomechanics and psychophysiology, widely used to study muscle strength, fatigue, and movement patterns.

Biomechanics and sport

Synchronous detection of muscle activity during movement. Enables the study of motor unit recruitment, assessing training effectiveness and isometric tension.

Group dynamics

Because the system pairs individual wireless modules, tension responses of two or more people can be monitored side by side without difficulty (e.g. during cooperative games).

Ambulatory and VR research

Without being tethered to a "desk" in the lab, participants can freely navigate VR simulators and have postural tension tested under realistic conditions (ecological validity).

Rehabilitation and ergonomics

Assessment of skeletal muscle tension at workstations and while driving, as well as a tool for objectively tracking progress in the rehabilitation process.
