Design of In-Vivo Communications that Allow Multiple Active Implants

Stimulation and Recording of peripheral neurons allowing haptic sensation of prosthetics is only one of many applications targeted by DARPA [7]. One challenge is the use of multiple electrode arrays in multiple fascicles of multiple nerves, making up to hundreds of electrode sites. In this paper, an in-vivo optimized serial communications approach is implemented which allows minimal wiring starting from a central hub to multiple smart tiny active modules with "city" addresses, each containing smart mixed signal custom ASICs with "city street" addresses and electrode sites with "house" addresses.
