Swarm Lab Seminar - Neural Dust: An Ultrasonic, Low Power Solution for Scalable and Chronic Brain-Machine Interfaces

Seminar: Swarm Lab | September 5 | 12:30-2 p.m. | 490H Cory Hall

A seamless, high density, chronic interface to the human brain is essential to enable clinically relevant applications such as brain-machine interfaces (BMI). Currently, a major hurdle in BMI is the lack of an implantable neural interface system that remains viable for a lifetime due to the development of biological response near the electrode. Recently, sub-mm implantable RF-based wireless neural interfaces have been demonstrated in an effort to extend system longevity, but the implant size scaling (and therefore density) is ultimately limited by the power available to the implant. Therefore, my project investigates an entirely new method of wireless power and data telemetry using ultrasound, which can address fundamental issues associated with using RF to interrogate miniaturized implants, and enable scaling of implants down to 10's of um. Such ultra-miniature as well as extremely compliant implantable neural interface has the potential to allow massive scaling in the number of neural recordings from the brain while providing a path towards truly chronic BMI.
