Rodent-scale open source programmable constant current deep brain stimulation system. Runs on a low power MSP430 microcontroller from Texas Instrumnents. Interfaces with an Android app using Near Field Communication (NFC).
- The Firmware/ directory contains the code which runs on the MSP430.
- The AppCode/ directory contains the Android Studio project and code for the NFC controller app.
- The PCBs/ directory contains the design files for the printed circuit board hardware.
The most recent version of the hardware is about 1/4" thick including a CR2032 battery, and a little larger than a quarter in footprint. Battery life is about 200 hours. In photos above, major grid is 1/2".
Current measurements (voltage over the series 10 K resistor) for a 90 µA, 60 µs, 120 Hz stimulation settings.
