About the HDSEMG PCB
HDSEMG is an open source PCB design by node9909, published on GitHub. It is a 2-layer board measuring 150 × 86.9 mm, with 207 components from 69 distinct parts.
Other key parts include the ADS1298_By_Oliver, Si8663, INA333AIDGKR, THS4521IDGKT and OPA333xxDBV. By type, the board carries 69 capacitors, 50 resistors, 26 connectors, 24 test points, 17 ICs and 6 jumpers.
From the project
design of a HD-SEMG system, using ads1298, Arduino DUE, ST32F4, INA333 adn AD8232
The hypothesis of the project was ”Can the AMAC performance level be improved in direct controlled (DC) myoelectric systems by exactly locating the location where the patient has the most amount of cover the agonist and antagonist of the residual limb during different hand gestures’’. The goal was to develop a device that can be used to confirm this hypothesis, the could be achieved by measuring the muscle potentials over the residual limb during different hand gestures (HD-SEMG recording)
