Abstract Details

2014, Doctor of Philosophy, Case Western Reserve University, EECS - Electrical Engineering.
In this research, a system is design to achieve the bi-directional neural activity recording and stimulation system for a sea slug. The system includes 3 different modules, a data compression algorithm, and a signal recording/stimulation ASIC. The neural spike detection compression algorithm developed by Ming-Husan Hsu is able to run in real time on a simple micro-controller and achieves an average compression ration of 20:1. The spike detection algorithm is verified by the correlation between pre-recorded signals from two buccal nerves (BN3 and B4/B5). In active period, the data showed high correlation value. The compression and re-construction algorithm can also achieve correlation value as high as 0.9 between original waveform and re-construction waveform. The 4 channel neural recording and stimulation ASIC is designed and fabricated in a CMOS 0.5 um process. The 3 serial amplifiers provide signal gain more than 10000 with an input refer noise of 2 uVrms. After the signal digitized by a 8-bit SAR ADC, it can be further processed by on board micro-controller or sent directly by on chip FSK transmitter. The stimulator can provide a variety of strength from 50 uA to 300 uA. The command feeds through the SPI port to control the ASIC function. The ASIC is designed capable of expanding input array size for large channel number. A implant unit integrated with ASIC and a compression algorithm loaded micro-controller, and a external tranceiver unit would complete the bi-directional system.
