Application of the Peltier-Seebeck effect for termical-electrical energy conversion as source for mobile device charging




Renewable energy, Applied Physics to engineering, Peltier Effect


This work states a viable option, using low-cost components and renewable energy, of building a phone charger with main source of energy from the difference of temperature between a human body and a heat sink, free of wires and/or external connectors. Using the Peltier-Seeback effect, to produce a potential difference from the broker junction in different heats, stabilizing and amplifying this with a circuit composed by simple components and of easy access, getting as the circuit output the average values of 5,02 V and 1.1A Such values may be taken in consideration as enough to recharge a smartphone battery, which the output values vary between 3.3V-5V and 0.7A-2A. This way, this shown study demonstrates the application of a thermal-physical effect on a common accessory of daily use, using as intermission the basic concept of engineering in what it refers to solving problems. Therefore, on electric energy shortage situations in remote places without electricity, there will be new search fronts, academic or not, that might be used as a broad way to allow the energy supply in home appliances of high tension, bringing energy supply to remote areas of any origin and contributing to the development of research on this area.
