About

The OpenNerve IPG will perform current-based neuromodulation, measure impedance, monitor electronic biosignals, and interface with chemical and physical sensors. Features include: * Four 4-contact or two 8-contact Bal-Seal connectors (16 total contacts) * 8 stimulation and 8 sensing channels, configurable among the 4 header connectors * Impedance measurement on all stimulation electrodes * Bluetooth Low Energy (BLE) communication * 2x rechargeable 400mAh Quallion QL0200I cells (primary cell option also available)

Electrical Specifications (V1.0)

• Sequential bipolar stimulation: select any of 8 channels or IPG case as anode and cathode
  
• Max stimulation current of ±5mA at 1.6kΩ (typical for SNS) or ±4mA at 2kΩ (typical for cVNS)
• Analog front ends (AFEs) configurable in hardware for multiple biosignals
• I2C connectivity in header for interfacing with digital sensors
• Neural recording front end for compound action potentials
