Development of a thermoelectric generator system for IoT applications

Waste heat is produced as a by-product from various manufacturing process. In most of the industry, low-temperature waste heat is released into the atmosphere instead of recovering it due to low-grade heat energy that is unable to provide any useful work. Thermoelectric generator (TEG) is one of the...
