| Research Abstract |
The goal of this project is to developtechnologies for integration of very fine out-of-plane silicon microprobe, silicon-dioxide microtubearrays with microelectronics using a “selective vapor-liquid-solid (VLS)growth”techniqueand three-dimensional microfabrication processes. Major achievements of the researchduring the project period includei) integration of microscalediameter probe electrode and tube arrays for simultaneous electrical recording, stimulation, and drug delivery system with a high spatialresolution, ii) realization of the microprobes with various lengths for three-dimensional recording/stimulationof neurons in a neuronal tissue, and iii) on-chip CMOS interface circuitry for high performanceelectronics includingamplifications and filtering of recorded neural signals, and data/power wireless transmission system. From these achievements,theproposed devicecould become apowerful technique to assist inunderstanding nervous systems and offerneural recording/stimulation and drug delivery in medical applications.
