Abstract

The Alfred Mann Foundation is developing a network of up to 850 injectable devices that have stimulating, sensing and communication capabilities. Each of the devices is coordinated via radio signals a hundred times a second by an external small module. All the devices are powered by lithium-ion rechargeable batteries. The stimulating, sensing, and communication circuits are designed to be highly power efficient to maximize battery life. The stimulator can be programmed to deliver pulses in the range: 5 muA to 20 mA, 7 mus to 2000 mus, and frequencies up to 4000 Hz. Bursting, ramping, and other stimulation features are included. The voltage sensor covers the range 10 muV to 1.0 V with bandpass filtering and data analysis. The implant also contains sensors for pressure, temperature, DC magnetic field, and distances between implants
