Currently, an increasing demand for autonomous sensors and systems with wireless radio connection and autonomous energy supply can be observed. This is in part due to the strong trend towards continually smaller mobile systems and the increasing market for “wearables”.

The energy supply of such systems by means of batteries or cables is often too complicated or complex. One solution provides the on-site energy generation from the environment – the so-called energy harvesting. Depending on the requirements and environment, it can be realized for example by solar cells, thermoelectric or piezoelectric materials. Here, new piezoelectric materials and technologies for their production are being introduced to convert mechanical energy (deformation, vibration) into electrical energy.
