The OpenNerve platform

The core implantable pulse generator (IPG) or equivalent development board provides current-driven stimulation (square waves up to 1.2kHz, low frequency sine waves 1-15 Hz), records analog biosignals such as EMG, ECG, and eCAPs, and has digital in-body communication for advanced biosensors or networked devices. Several stimulation / recording leads and digital sensors are being developed by OpenNerve, or researchers are welcome to bring their own leads (Bring your own leads). Bluetooth Low Energy (BLE) allows real-time data streaming and control; a custom inductive charger allows safe recharging.
