Metal-embedding method helps tiny sensors function in extreme environments

University of Wisconsin-Madison mechanical engineers have developed a method for fabricating packages of tiny sensors that measure temperature more accurately than bulk thermocouples. Inserted unobtrusively in critical locations, these metal-embedded micro-thin film thermocouples could more effectively monitor conditions and diagnose problems during manufacturing processes such as injection-molding or die-casting.
