Abstract :
This paper presents the design, fabrication and functional testing of a fully implantable, flexible, Parylene-enabled neurostimulator that features single channel wireless stimulation capability. The system comprises a CMOS stimulator chip, a fold-and-bond RF coil, two platinum electrodes, and discrete capacitors. The MEMS components are fabricated with a Parylene-metal skin technology, and the system assembly is achieved by interconnecting individual components together on a Parylene substrate with silver epoxy. The functionality of the integrated system is verified using a telemetry link setup, and single-phase pulses with amplitudes ranging from 7 to 8.5 V are detected.
