Abstract

A CMOS gas-sensitive field-effect transistor (Gas-FET) is proposed for noninvasive diabetes detection. The Gas-FET was fabricated in the GlobalFoundries 0.18μm 1P6M process with a lateral control gate and a floating gate to set operating point and gas sensing sensitivity, respectively. ZnO nanorods were used as the sensing material and deposited on top of the chip using a hydrothermal process at 80°C. Room-temperature acetone sensing down to sub-ppm level is demonstrated to enable noninvasive diagnosis of diabetes in exhaled breath. A dual-mode integrated readout circuit is also proposed to improve the sensor gas discrimination ability through the acquisition of 2-dimensional information by every single Gas-FET sensor.
