Abstract: A brain-machine interface (BMI) is a system that can both sense and modulate abnormal electrical activities in the brain, in hope of helping patients with conditions ranging from motor disabilities to depression. Currently, a major hurdle in BMI technology is the lack of an implantable neural interface system that remains viable for a significant fraction of the patient's lifetime due to the development of biological response near the electrodes. A seamless, high-density, chronic interface to the brain that enables clinically relevant applications would be a game changer. In this talk, we will cover general challenges, limits, and opportunities in designing such electronics to interface with the brain. We will touch upon Berkeley's efforts on this front, with a particular focus on key concepts and recent progress with a distributed, ultrasonic backscatter system we term neural dust.
