This paper reports the development of optical lever based parylene cantilevers for biochemical sensing. A simple but effective process to fabricate parylene cantilevers using Tetramethylammonium Hydroxide (TMAH) bulk-micromachining was demonstrated. A scheme of using anchoring holes was employed to prevent the peeling off of parylene during TMAH etching.(More)
—This paper reports the development of microma-chined thermal shear-stress sensors for underwater applications. The thermal shear-stress sensor is a polysilicon resistor sitting atop a vacuum-insulated nitride diaphragm. Special challenges for underwater measurements, such as the waterproof coating and minimization of pressure crosstalk, have been(More)
Natural inter-neuronal communication is mediated primarily via neurotransmitter-gated ion channels. While most of the methods for neural interfacing have been based upon electrical stimulation, neurotransmitter-based approaches for the spatially and temporally controlled delivery of neurotransmitters are relatively new. Methods of neurotransmitter(More)
