A Study on the Implant Interface of Brain-Computer Interface Technology in the THz Band

ETSI SmartBAN defines the basic access of an ad hoc personal wireless network for wearables around the human body. SmartBAN provides a communication interface for such wearables and a monitoring station known as the hub. In the next phase of development for SmartBAN, new use cases are explored. In particular Brain-Computer Interface (BCI) with implant devices. Recording neural activity with high spatial and temporal resolution has been elusive as it requires bulky and expensive equipment or highly invasive implants with limited throughput. To overcome such limitations, the use of THz technology is studied as it enables a small form factor and very high throughput. The paper presents an initial study on this promising technology for in-body applications and in particular the next generation of BCI systems.
