Piezoelectric Energy Harvesting
Bulletin of Science, Technology & Society, 2008Providing efficient and clean power is a challenge for devices that range from the micro to macro in scale. Although there has been significant progress in the development of micro-, meso-, and macro-scale power supplies and technologies, realization of many devices is limited by the inability of power supplies to scale with the diminishing sizes of ...

Wind energy harvesting with a piezoelectric harvester
Smart Materials and Structures, 2013An energy harvester comprising a cantilever attached to piezoelectric patches and a proof mass is developed for wind energy harvesting, from a cross wind-induced vibration of the cantilever, by the electromechanical coupling effect of piezoelectric materials. The vibration of the cantilever under the cross wind is induced by the air pressure owing to a

On the Performance Improvement of Piezoelectric Energy Harvesters
International Journal of Mechanical Engineering and Robotics Research, 2016Among the available solutions to harvest energy from vibrating and non-vibrating sources, piezoelectric bimorphs seem to be a suitable choice due to their capability to directly convert applied strain energy into usable electric power. This work reviews the techniques adopted to increase the specific power per unit of volume of piezoelectric scavengers.

A Review on Piezoelectric Vibration Energy Harvesters
2023Piezoelectric energy harvesters are attractive for developing self-generating power. The combination of sparse energy and the huge weight of batteries poses the most censorious problem for individuals having high electricity demands in remote areas and who are already carrying hefty loads (such as explorers or field scientists).

Piezoelectric Energy Harvesting
2017The ability to deliver sustainable electric power to micro-electro-mechanical systems (MEMS) or a wireless system network by energy harvesting is attractive not only because of the cost of batteries but also because it removes the additional time and cost that is necessary to replace and maintain the batteries, including the installation of complex ...

Tunable interface for piezoelectric energy harvesting
2014 IEEE 11th International Multi-Conference on Systems, Signals & Devices (SSD14), 2014The so called Synchronous Electric Charge Extraction (SECE) interface is an electrical circuit to extract energy from a piezoelectric transducer and to put it onto a storage device like a large capacitor. The advantage of the SECE interface is the load independent power transfer.

Piezoelectric energy harvesting
Energy Conversion and Management, 2009Abstract Piezoelectric materials can be used to convert oscillatory mechanical energy into electrical energy. This technology, together with innovative mechanical coupling designs, can form the basis for harvesting energy from mechanical motion. Piezoelectric energy can be harvested to convert walking motion from the human body into electrical power.
