A thermal microflowmeter has been integrated into a bulk micromachined recording probe to monitor drug delivery in the central nervous system at the cellular level Based on trench refill and chemical mechanical polishing (CMP) processes, the drug delivery probe achieves a 50 mum2 cross-sectional area and partial or all dielectric channel sidewalls. The flowmeter uses an arsenic-doped polysilicon heater/sensor...
This paper describes microassembly techniques for an out-of-plane three-dimensional microelectrode array for neural stimulating and recording in the central nervous system. An interlocking mechanism has been introduced into the microassembly components to facilitate the process, increase the robustness of the assembled device and improve the yield of the overall system. In-vivo testing has demonstrated...
A thermal microflowmeter has been integrated into a bulk-micromachined recording probe to monitor drug delivery in the central nervous system at the cellular level. The flowmeter uses an arsenic-doped polysilicon heater/sensor supported on a dielectric membrane over the flow channel. It is capped by a vacuum-sealed microchamber to minimize heating of the surrounding tissue and maximize heating efficiency...
An interface providing multi-point microstimulation and position sensing has been developed for a cochlear prosthesis, integrating a MEMS-based electrode array with signal-processing electronics. The array incorporates piezoresistive polysilicon sensors for position and tip contact to minimize insertion damage and optimize implant placement. The signal-processing chip (2.4mm times 2.4mm) operates...
