Keywords:
thermal energy conversion,Low-Grade Heat Utilization,Nonequilibrium Thermodynamics
In recent years, unconventional approaches to thermal energy utilization have emerged, including systems that harvest energy from temporal fluctuations in ambient temperature, systems capable of spontaneously generating thermal gradients, and systems that drive chemical reactions through thermally excited carriers in molecules or semiconductors. A common characteristic of these approaches is their ability to utilize relatively low-grade heat. Beyond converting thermal energy into electrical power, some of these systems have also been reported to exhibit cooling effects during operation, suggesting the existence of previously unexplored thermodynamic processes.The objective of this symposium is to establish the fundamental scientific principles underlying these emerging thermal energy conversion phenomena. Discussions will encompass a broad range of perspectives, including nonequilibrium thermodynamics, electrical and electronic engineering, materials science, and chemistry. By leveraging the interdisciplinary nature of the Japan Society of Applied Physics, the symposium will foster cross-disciplinary dialogue, deepen our understanding of the underlying mechanisms, and provide a comprehensive perspective on future research directions and technological opportunities in this rapidly developing field.
