Electricity Generation Using Nano Generator

Abstract

The usefulness of most high technology devices such as cell phones, computers, and sensors is limited by the storage capacity of batteries. .In the future, these limitations will become more pronounced as the demand for wireless power outpaces battery development which is already nearly optimized. We need to develop electricity generating techniques with the help of wasted human energy which is in the form of mechanical pressure and vibration for our better future .Thus, new power generation techniques are required for the next generation of wearable computers, wireless sensors, and autonomous systems to be feasible. Nano generators are excellent power generation devices because of their ability to couple mechanical and electrical properties. For example, when an electric field is applied to Nano sheets a strain is generated and the material is deformed. Consequently, when a Nano sheets is strained it produces an electric field; therefore, Nano generators can convert ambient vibration into electrical power. Piezoelectric materials have long been used as sensors and actuators; however their use as electrical generators is less established. A piezoelectric power generator has great potential for some remote applications such as in vivo sensors, embedded MEMS devices, and distributed networking. Developing piezoelectric Nano generators is challenging. Piezoelectric properties are controlled/tuned by externally applied force/pressure, such as diode, strain sensor and strain-gated logic unites, which are a new field called piezotronics. Our paper presents a practical analysis to increase the power generation using Nano generators
