First Steps Towards a Self-Sufficient Energy Supplier

The energy from vibrations and oscillations can be utilized with the piezoelectric effect. The sturdy, plastic-laminated DuraAct piezo transducers from PI Ceramic (PIC) are ideally suited to this. They are easy to handle and process even displacements in the millimeter range. At the same time, they are especially reliable and durable.

EH Evaluation Kit i4c

A newly available evaluation set contains corresponding transducer and storage electronics in addition to the piezo element. The energy harvesting system works in a wide frequency range from a few hertz to several thousand hertz. For a short time, it achieves an electrical output power of up to the milliwatt range, which can be tapped at a stable output voltage of between 1.8 and 5 V. This can be used to operate many commercially available electric circuits and systems.

Once a system has been successfully qualified, it can then be optimized for a specific application: The size and frequency range of the piezo transducer can be adjusted to the application, and the electronics can be adapted as desired.
