In the coming years, the use of low-powered integrated circuits in self-powered systems and the Internet of Things will require millions, if not billions of sensors to be powered. This project aims to meet that need by exploiting temperature gradients through the use of thermoelectric generators. Thermoelectric generators are solid state devices consisting of two ceramic plates separated by a number of small, semiconductive, coupled rods. In accordance with the Seebeck effect, temperature variations between the two plates are converted into electrical power, which can then be harvested for small-scale electronic devices. The aim of this research is to determine whether it is possible to calculate the power available for a given space based solely on the temperature gradient measured within that space. This is being accomplished by measuring the current and voltage responses of a series of thermoelectric generators to various temperature gradients and directly relating those responses to power availability in order to develop a deterministic model. In addition, the temperature gradients are being determined by measuring common, household surfaces, such as desks or chairs, in common, everyday environments, and comparing these temperatures to the relative temperature of the air. If this project proves successful, it will directly contribute to future projects aimed at exploiting this temperature gradient/power availability relationship for low-powered integrated circuits.
