Thermoelectric Power Generator

IME and NUS researchers have developed a thermoelectric power generator for energy-harvesting applications. By exploiting Seebeck effect to generate electrical power and employing Si nanowires with polyimide as the filling material, the generator can produce 300x higher power than that using silicon dioxide filling. Compared to commercial micro-pelt technologies, the new generator is highly scalable, readily integrated with other CMOS ICs and is expected to bring down the cost of power generation by 10x.
