Abstract
A flexible thin film impedance sensor has been developed. Device manufacturing process and preparation of test wafers are described. Sensors with ring shaped Au electrodes have been fabricated on a polyimide substrate using Si wafer as a temporary substrate. The sensors have been characterized by means of Agilent 4294A analyzer and tested in measurements of impedance of human skin, Si wafers and other materials. Results of indirect measurements of samples covered with dielectric layer (SU-8, glass) confirm advantages of the sensors.
