A Programmable Intraocular CMOS Pressure Sensor System Implant

摘要

In this contribution we present a programmable intraocular pressure sensor system implant integrated on a single CMOS chip. It contains on-chip micromechanical pressure sensor array, a temperature sensor, readout and calibration electronics, a μC-based digital control unit, and an RF-transponder. The transponder enables wireless data transmission and wireless power reception, thus making batteryless operation feasible. The chip has been fabricated in a 1.2 μm n-well CMOS process complemented by additional processing steps.
