A lot of critical research in nanotechnology is being carried out all around the world. A wide range of applications are feasible in real- time using nanotechnology starting from medical to space research. It is going to make a huge impact in our lives. One such application is in the field of scavenging energy from noise. As noise pollution is becoming a great problem in our present day to day lifestyle. So to use this wasted energy in a much more useful manner we perform an analysis of energy extraction feasibility by use of Nanofiber-based piezoelectric devices performance data. We have used various acoustics and energy transfer formulas of these Nano devices to perform mathematical simulation of it, by taking into account real-time noise level survey data sheets. This shows its possibility of using Nano devices with Nanofiber-based piezoelectric devices. Here we have proved its actual practical feasibility from our simulation results.

Introduction: Nanotechnology is the latest and most versatile field of research. Nanotechnology is defined as the study of manipulating matter on an atomic and molecular scale. It deals with developing devices and structures at a dimension about 1 to 100 nanometer. Nanogenerators are those devices which can harvest mechanical energy using the PZT Nanofibers. Piezoelectric Nano Wire and Nanofiber based generators have potential uses for powering such devices through a conversion of mechanical energy into electrical energy. Throughout the world noise pollution adversely affects the lives of millions of people. Studies have shown that there are direct links between noise and health. Problems related to noise include stress related illnesses, high blood pressure, speech interference, hearing loss, sleep disruption, and lost productivity. Noise Induced Hearing Loss (NIHL) is the most common and often discussed health effect, but research has shown that exposure to constant or high levels of noise can cause countless adverse health effects. (We can see some of these side effects analysis by U.S Environmental protection agency at: www.epa.gov/air/noise.html.). So our motivation comes here. Is there no way to make this noise pollution a boon to society in some way? This can be made possible with Nanotechnology help. Here we want to use the noise energy to operate Nano devices for example nanobots by using some mechanism like converting mechanical pressure (present in noise) to electrical form. This can be done now using piezo-nanofiber (PZT) which is already available or tiny micro piezo-crystals that can convert enough amount of sound energy to electrical form to operate a cluster of nanobots. In our study we have made a simulation of what level of intensity of noise can produce what amount of mechanical pressure by taking into account the some of the governmental survey data available from internet about noise intensity level at various places. These Nano devices can also help control noise pollution by monitoring it in real time. II. Literature Survey: Research all around the world are going no to find clean and renewable sources of energy. And noise pollution is a serious problem to the environment and human health. Noise health effects describe problems in both health and behaviour. Unwanted sound (noise) can damage physiological and psychological health. Chronic exposure to noise may cause noise-induced hearing loss. High noise levels can contribute to cardiovascular effects and exposure to moderately high levels during a single eight hour period causes a statistical rise in blood pressure of five to ten points and an increase in stress and vasoconstriction leading to the increased blood pressure noted above as well as to increased incidence of coronary artery disease. A 2005 study by Spanish researchers found that in urban areas households are willing to pay approximately four Euros per decibel per year for noise reduction. An impact of noise on animal life is the reduction of usable habitat that noisy areas may cause, which in the case of endangered species may be part of the path to extinction. Noise
