Involves, real-time, high resolution measurement of the electromyogram (EMG) of two muscle groups associated with hand and wrist.
- opponens pollicis (thumb flex)
- pronator quadratus (wrist rotate)
This dual channel EMG data is sampled at 2000Hz and wirelessly transmitted at 2.4GHz, using a bidirectional digital communications scheme (BioNomadix – BIOPAC Systems, Inc.). Data is received and then integrated and further conditioned to drive gripper and wrist servo motors.
