An Efficient Energy Absorbing Structure Inspired by Energy Harvesting Device

Tree-inspired piezoelectric energy harvesting

We design and test micro-watt energy-harvesters inspired by tree trunks swaying in the wind. A uniform flow vibrates a linear array of four cylinders affixed to piezoelectric energy transducers. Particular attention is paid to measuring the energy generated as a function of cylinder spacing, flow speed, and relative position of the cylinder within the array. Peak power is generated using cylind...

An efficient Piezoelectric energy-harvesting interface Circuit

Energy harvesting is an emerging technology with applications to handheld, portable, and implantable electronics. Harvesting ambient vibration energy through piezoelectric (PE) means is a popular energy-harvesting technique that can potentially supply 10’s-100’s of μW of available power [1]. One of the limitations of existing PE-harvesters is in their interface circuitry. Commonly used full-bri...

A periodic folded piezoelectric beam for efficient vibration energy harvesting

Periodic piezoelectric beams have been used for broadband vibration energy harvesting in recent years. In this paper, a periodic folded piezoelectric beam (PFPB) is introduced. The PFPB has special features that distinguish it from other periodic piezoelectric beams. The Adomian decomposition method (ADM) is used to calculate the first two band gaps andtwelve natural frequencies of the PF...

Improvement of Solar Still Productivity by Energy Absorbing Plates

A solar still is a viable option when the demand of potable water does not exceed more than 3 litres. Enhancement in distillate output from the solar still is a main goal of many researchers all over the world. In this research, the effect of copper and aluminium plates on distillate output is investigated experimentally as well as theoretically at different water depths under the same climate ...
