Open Nerve

The OpenNerve project is an advanced open-architecture, open-source implantable neuromodulation system. Funded by the National Institutes of Health (NIH) under the Human Open Research Neural Engineering Technologies (HORNET) initiative, this project focuses on developing a sophisticated Implantable Pulse Generator (IPG) platform. The IPG is designed to perform current-based neuromodulation, measure impedance, monitor electronic biosignals, and interface with chemical and physical sensors. Our team at Focus is responsible for the electronics design, ensuring the system is robust, scalable, and adaptable for a wide range of neuromodulation therapies.
