Setup and tests of piezotronic devices based on ZnO deposited by atomic layer deposition Piezotronic devices convert a mechanical signal into an electric signal. These convert an applied pressure into a measurable electric signal through piezoelectric effect. They are usually used as sensors in all sorts of configurations in micromechanical systems. The aim of this master thesis is to make a stress/strain sensor that would be able to measure piezoelectric signals on a nano scale, working with thin films on flexible substrates. This will allow us to measure sensitive and fast occurring stimuli. To achieve our goal we first investigate the piezoelectric effect and its behaviour with regard to the different materials used as electrodes. After determining the set up with the best possible response, the next objective is to be able to quantify the applied stress through the piezoelectric effect and test it with small applied forces. |
