Neural Dust: An Ultrasonic, Low Power Solution for Chronic Brain-Machine Interfaces

8 Jul 2013Dongjin SeoJose M. CarmenaJan M. RabaeyElad AlonMichel M. Maharbiz

A major hurdle in brain-machine interfaces (BMI) is the lack of an implantable neural interface system that remains viable for a lifetime. This paper explores the fundamental system design trade-offs and ultimate size, power, and bandwidth scaling limits of neural recording systems built from low-power CMOS circuitry coupled with ultrasonic power delivery and backscatter communication...
