Notes:
Chemical composition and uniaxial compressive stress are varied to observe their effect onthe current-voltage behaviors of ZnO based ceramics. Chemical composition variation produces twokinds of ceramics showing ohmic and nonohmic current-voltage behaviors. The current at a fixedvoltage is increased with the increase of the compressive stress for both ceramics. Ceramics withnonohmic behavior shows better reversible return of current-voltage curve when the appliedcompressive stress is removed from the ceramic than those with ohmic behavior do. We found out anappropriate chemical composition showing linear relation between current and stress at a fixedvoltage as a potential application of the ceramic material to pressure sensor
