Piezoelectric ceramic actuators have wide application prospects in precision positioning and measurement technology, but its hysteresis characteristics cause a lot of restrictions to their ...

Vibration energy harvesting with piezoelectric materials is of practical interest because of the demand for wireless sensing devices and low-power portable electronics without external power supply.

Based on discretized electrode, a novel piezoelectric ceramic disk with a new form of electrode coating is proposed, where the created multiple electrical ports are linked into a series configuration.
