The present invention provides a method and device using CMOS and MEMS fabrication techniques for making an integrated microneedle device with integrated circuits. Merely by way of example, the technology can be applied to bio and chemical sensing, and other bioMEMS applications. In some embodiments, the integrated circuits are completed using standard IC processes. For example, an array of microneedles are fabricated on top of the IC substrate followed by formation of micro fluidic channels in the substrate. On-chip integrated circuits enable real-time sensing and intelligent drug delivery.
