Recent work has developed programmable micro-coil neural probes integrating CMOS technology with the micro-coil design. However, the design did not utilize multi-turn micro-coil designs to reduce the necessary stimulation current. This work proposes a neural probe that co-optimizes the micro-coil design with CMOS micro-coil current drivers to maximize the induced electric field gradients. The proposed probes and characterized current of 9 mA for two micro-coils on a 3.5 V supply. Preliminary in-vitro testing with mouse olfactory bulb slices and a commercial MEA show the probes are capable of producing changes in neural behavior.
