Abstract

ZnO is well known semiconductor material with high band gap as well as piezoelectricity. Because of its high performance of electromechanical behavior, ZnO based piezoelectric devices have taken great attention from many research groups. However, ZnO should be grown on a flexible substrate so as to allow its flexibility. Since cellulose is renewable, flexible and biocompatible, ZnO is grown on cellulose by hydrothermal process, then a novel flexible piezoelectric material. We report the fabrication and strain sensor behavior of cellulose ZnO hybrid nanocomposite(CEZOHN) In this research, simple piezoelectric strain sensor based on CEZOHN is made by directly stretching it and by boding it on a cantilever. Its performance is measured in terms of longitudinal and bending strain. This strain sensor shows a good linearity.
