An Intermittent Self-Powered Energy Harvesting System From Low-Frequency Hand Shaking

Fully Self-Powered Electromagnetic Energy Harvesting System

This paper describes the use of piezoelectric polymers in order to harvest energy from people walking, together with the electronics needed to increase energy transfer and storage efficiency. An electrostatic generator was also included in order to increase energy harvesting. There have been independent solutions in increasing the harvesting efficiency either on the mechanical harvester or on i...

A low frequency rotational energy harvesting system

This paper presents a rotary power scavenging unit comprised of two systems of flexible beams connected by two masses which are joined by means of a spring, considering a PZT (QP16N, Midé Corporation) piezoelectric sheet mounted on one of the beams. The energy harvesting (EH) system is mounted rigidly on a rotating hub. The gravitational force on the masses causes sustained oscillatory motion i...

Energy Harvesting for Self-Powered Nanosystems

Address correspondence to [email protected] ABSTRACT In this article, an introduction is presented about the energy harvesting technologies that have potential for powering nanosystems. Our discussion mainly focuses on the approaches other than the well-known solar cell and thermoelectrics. We mainly introduce the piezoelectric nanogenerators developed using aligned ZnO nanowire arrays. This is...

Energy Harvesting for Self Powered Sensor Systems

Wireless autonomous sensor systems become steadily standard components in our environment and they become smaller, cheaper and more sophisticated. Energy harvesters fabricated by micro-system technology can realize the autonomy of those systems. An overview of latest results and remaining challenges will be given with the focus on vibration energy harvesters. These harvesters are of specific in...
