A review of piezoelectric energy harvesting based on vibration

Abstract

This paper reviews energy harvesting technology from mechanical vibration. Recent advances on ultralow power portable electronic devices and wireless sensor network require limitless battery life for better performance. People searched for permanent portable power sources for advanced electronic devices. Energy is everywhere around us and the most important part in energy harvesting is energy transducer. Piezoelectric materials have high energy conversion ability from mechanical vibration. A great amount of researches have been conducted to develop simple and efficient energy harvesting devices from vibration by using piezoelectric materials. Representative piezoelectric materials can be categorized into piezoceramics and piezopolymers. This paper reviews key ideas and performances of the reported piezoelectric energy harvesting from vibration. Various types of vibration devices, piezoelectric materials and mathematical modeling of vibrational energy harvestings are reviewed.

Piezo-Electrochemical Energy Harvesting with Lithium-Intercalating Carbon Fibers

“…5 Kinetic energy is often converted into electrical energy using piezoelectric harvesters that have operating frequencies of typically 100-1,000 Hz, 3 are small, light and have advantageous energy densities. 1,6 Lead zirconate titanate (PZT) piezoceramics have high piezoelectric coupling and energy conversion rate, but are too brittle to take general shape. 1 Rechargeable batteries are the primary electrical energy-storage medium for today's mobile and wearable electrical devices, although with inherent demand of external input in form of contacting and charging.…”

Li-ion batteries are particularly attractive for their high specific energy, high operating voltage and very slow self-discharge, but efforts are made to increase their rate capability.…”

Implementing an energy harvesting technology within the concept of Smart city

“…Energy harvesting is defined as capturing minute amounts of energy from one or more of the surrounding energy sources, accumulating them and storing them for later use. Micro energy harvesting technology is based on mechanical vibration, mechanical stress and strain, thermal energy from furnace, heaters and friction sources, sun light or room light, human body, chemical or biological sources [14]. The piezoelectric material converts mechanical vibration into electrical energy.…”

Pengujian Sistem Konversi Energi Suara menjadi Energi Listrik menggunakan Piezoelektrik

“…Bahan piezoelektrik adalah suatu bahan yang apabila diberikan tekanan mekanik akan menghasilkan medan listrik, sebaliknya apabila medan listrik diterapkan pada bahan piezoelectric akan terjadi deformasi mekanik. Sifat yang reversible ini membuat material Piezoelectric dapat berfungsi sebagai transduser dan aktuator [6].…”
