This WE-Heraeus Seminar on Transverse Effects in Thermoelectric Systems will bring together practitioners of thermoelectric technologies in academia and industry for 3 days of talks, posters and discussions addressing the emergent area of transverse thermoelectrics. With uses in carbon-free energy generation, cooling, sensing and process monitoring, transverse thermoelectrics stands to play a role in several of society’s most pressing technological challenges: generating green energy, cooling our infrastructure, maximizing the efficiency and safety of our chemical and power production, and exploring space.
