All elements of the gage are thin films, deposited on the surface by sputtering or an equivalent process. The gage comprises a plurality of thermocouple junctions connected as a differential thermopile, with hot and cold junctions on the two faces of a planar thermal resistance element. Electrical insulating and protective layers are deposited between the surface and the gage, and over the exterior of the gage. The gage output signal is a voltage indicative of heat flux.application/pdfen-USPatenthttp://pimg-fpiw.uspto.gov/fdd/94/799/047/0.pdf7109057136/225374/29374/30374/E17.015G01K17/20H01L35/084779994
