C2.1 - Bandwidth Improvement for Vibration Energy Harvesting devices

Abstract

This contribution provides a technology overview on techniques to enlarge the bandwidth of vibration energy harvesting devices. In general a broadband device is demanded, such a device would be easily applicable on many vibration sources without any adoption. Up to date such a system is not available. However, improving the broadband characteristic has been investigated intensely in the recent years. This paper introduces vibration energy harvesting briefly and provides a detailed classification of the various broadband techniques.
