Abstract

This work focusses on the development of a ZnO based piezo-resistive polymer cantilever sensor platform. Two different approaches have been taken, one based on Al-doped ZnO transistor (TFT) embedded in a polymeric micro-cantilever and another with a ZnO nanowire embedded microcantilever. Low Young´s modulus of SU-8, low process temperature and high strain sensing capability of ZnO makes this platform an attractive option for sensor applications. For both the approaches, electromechanical and mechanical characterization results are reported in this work.
