Thinner, tougher heat flux sensors Researchers from the Department of Physics at the University of Tokyo have designed a heat flux sensor that can measure heat flux — the amount of heat that passes through a material — using a manufacturable, flexible thin film with circuits etched in a way that increases the anomalous Nernst effect (ANE). ANE turns heat into an electrical signal using ... » read more
