Abstract :
A fully-integrated microsensor chip allows continuous monitoring of concentrations of blood gases (pH, pO/sub 2/, pCO/sub 2/), ions, and biomolecules, and a conductometric measurement. The chip monitors 7 different chemical properties and includes temperature control and an EPROM. It occupies 25.7 mm/sup 2/ in a standard 1.2 /spl mu/m CMOS process including chemical sensor postprocessing and operates at 5 V.
