Influence Of Conduction Shape Factor In Subterranean Cooling For A Thermoelectric Energy Harvesting System At Asphalt Pavement: An Experimental Investigation

This research study’s primary motivation is to study the practicality and feasibility of energy harvesting or energy scavenging using ambient energy such as heat absorbed by asphalt pavement to provide electrical power for small electronic circuits or devices, making them self-sufficient. Therefore,...
