As smartphones become more and more popular, more energy is used to charge these devices. Creating energy through thermoelectric generators could be very effective and create virtually free energy. We attempted to create a device in the form of a headband to generate enough electricity to charge a small device such as an iPhone using Peltier modules. Peltier modules use the Seebeck effect to generate electricity, which is an effect that creates energy when there is a temperature difference between two conductive materials. The heated electrons flow towards the the cooler electrons, creating electricity. Our first experiment was to demonstrate how body heat could be best utilized to produce energy using a wearable thermoelectric generator. Our hypothesis was that if a Peltier module was to be placed on the chest, near the heart, and/or underarms, we could most effectively be able to generate electricity through the Seebeck effect. Our original tests were conducted on areas of the upper torso such as the abdomen and solar plexus; however we then switched to areas on the head as test results were much more consistent and viable. Given these results, we decided that a wearable head device would be most effective. According to research done by Lifehacker, the amount of energy used to charge the amount of iPhone 5’s in one year amounted to enough to power a city with the population of 180,000.
