Problems solved by technology

However, piezoelectric materials can be brittle, and stiff or inflexible, which can adversely affect the performance of piezoelectric energy harvesting devices
[0006] For example, due to these characteristics, the efficiency of the conversion of kinetic energy to electrical energy by piezoelectric energy harvesting devices is reduced
Additionally, piezoelectric energy harvesting devices may be less durable and / or may not be suitable for many environments
Additionally, the cost, amount of time, and / or difficulty associated with fabricating piezoelectric energy harvesting devices is high, which may not be suitable for some applications

Abstract

The invention discloses an energy collecting device and a method for forming the energy collecting device. In the embodiments of one or a plurality of devices, the energy collecting device comprises a ferroelectric material, and a first electrode and a second electrode which are adjacent to the ferroelectric material.

Description

technical field [0001] The present invention relates to energy harvesting devices and methods of forming energy harvesting devices. Background technique [0002] Various external energy sources may exist within the environment, such as vibrations, light variations, temperature variations, and / or kinetic energy, among other types of external energy sources. Energy harvesting devices are capable of converting energy from one or more of these external energy sources into electrical energy. That is, an energy harvesting device can be a power source for generating electrical energy from one or more external energy sources (eg, within the environment surrounding the energy harvesting device). [0003] Because energy harvesting devices can generate electrical energy from an external energy source, energy harvesting devices have a longer lifespan than other power sources, such as batteries. Furthermore, the amount of cost, time and / or labor associated with maintaining the energy h...
