Microsystems can offer new and convenient ways to interact with biological systems in vivo and in vitro and our lab. is constructing some building blocks from component technology (such the"flexible CMOS") to MEMS-inside systems (such as a "nanoMRI") to facilitate these interaction. For the former, I'll use the example of a flexible 8" 0.18um Mixed Signal/RF CMOS circuit technology for medical implant applications. CMOS silicon substrate is thin down to 1um in thickness. Functionality of electronic devices and circuits are demonstrated with transistors and RF circuits made by this flexible technology and stress effects on these electronic devices are characterized for pre-compensation in the circuit designs. Further implementation of CMOS-compatible sensing devices may allow us to realize compact and fully integrated medical implants. I'll also describe the MEMS devices and CMOS circuit co-simulation/co-optimization environment "SIMPLI" we developed to facilitate the design of integrated Microsystems on Cadence EDA tools. On the system level, I'll use a desk-top, cell-resolution nano-MRI/MRS system currently under development in our lab as an example. Leveraged by scaling laws, MRS/MRI microsystems could be an inexpensive way to perform long-term, 3D studies of clusters of live cells.
