Abstract
Ambient energy harvesting is also known as energy scavenging or power harvesting, and it is the process where energy is obtained from the environment. A variety of techniques are available for energy scavenging, including solar and wind powers, ocean waves, piezoelectricity, thermoelectricity, and physical motions. For example, some systems convert random motions, including ocean waves, into useful electrical energy that can be used by oceanographic monitoring wireless sensor nodes for autonomous surveillance. Ambient energy sources are classified as energy reservoirs, power distribution methods, or power-scavenging methods, which may enable portable or wireless systems to be completely battery independent and self sustaining. The students from different disciplines, such as industrial technology, construction, design and development and electronics, investigated the effectiveness of ambient energy as a source of power. After an extensive literature review, students summarized each potential ambient energy source and explained future energy-harvesting systems to generate or produce electrical energy as a support to conventional energy storage devices. This article investigates recent studies about potential ambient energy-harvesting sources and systems.

Summary
Today, sustaining the power requirement for autonomous wireless and portable devices is an important issue. Power scavenging may enable wireless and portable electronic devices to be completely self-sustaining, so that battery maintenance can be eventually removed. Systems continue to become smaller, yet less energy is available on board, leading to a short run-time for a device or battery life. Researchers continue to build high-energy density batteries, but the amount of energy available in the batteries is finite and low, which limits the life time of the systems. The source of information for each technique is given in the third column of the table Though this comparison is not comprehensive, it does provide a broad range of potential methods to scavenge and store energy from a variety of ambient energy sources.
