Wireless Neuro-Actuator Prosthetic uses BioNomadix EMG

A wireless neuro-actuator prosthetic was created using BIOPAC's wireless hardware and additional custom hardware. The electromyogram of both opponens pollicis (thumb flex) and pronator quadratus (wrist rotate) was recorded from the Subject's palms and wrists, and the real-time, high-resolution surface EMG signal was processed to control the grip and rotation of remote handgrips.

For each arm, five disposable surface EMG electrodes (EL503) were connected with short 15 cm leads (BN-EL15-LEAD2 and BN-EL15-LEAD3) to a BioNomadix Wireless EMG transmitter/receiver set.

EMG data was sampled at 2000 Hz and wirelessly transmitted at 2.4 GHz via bidirectional digital communications. EMG signal output was switched to the alternate mode for Integrated RMS (Envelope Detection Mode) and further conditioned to drive gripper and wrist servo motors.

BioNomadix wearable physiology monitoring devices offer a fully-wireless recording system for life science research. Data can be recorded from two independent sites for a variety of signals, including ECG, EEG, EOG, EMG, EGG, EDA, Respiration, Pulse, Temperature, Impedance Cardiography, Strike Force, Goniometry, Accelerometry, and Gyro.
