To date, there are no clinically available cortical neural implants which wirelessly transmit the full neural signal at an adequate data transfer rate while managing power dissipation limits. The current work addresses power consumption and data bitrate requirements using wideband transmission, omitting the use of a constant carrier wave, and short impulses to transmit pulse width modulation encoded data, transmitting more effective bits per cycle. An inductive link is used, reducing power consumption compared to radio frequency transmitters. 1 Msample/s transmission rate with 6 bits of resolution is demonstrated, providing proof-of-concept for a system that transmits the full neural signal outside the body. Such a system enables extracorporeal processing of the neural signal, potentially lending itself to applications such as brain-computer interfaces and diagnosis and treatment of neurological disorders. The intelligence of the system can be adjusted according to scientific advancements, without being limited to processing power onboard the implant.
