Abstract：

A　Cu-Ni　thin　film　heat　flux　sensor　had　been　fabricated　on　a　0.05mm　thick　polyimide　film　substrate　by　vacuum　coating　technology.　The　overall　dimension　of　the　sensor　was　8　mm　long　and　4　mm　wide.　A　thermopile　and　a　thermocouple　were　arranged　on　the　substrate　to　measure　both　heat　flux　and　surface　temperature.　The　thermopile　had　18　thermocouple　junctions　which　formed　9　pairs　of　differential　thermocouples　and　were　covered　by　two　different　thickness　of　thermal　resistance　layers.　This　research　carried　out　static　and　dynamic　tests　of　the　thin　film　heat　flux　sensor.　Seebeck　coefficient　of　thermocouple　is　19.3761μV/(°C).　Sensitivity　of　the　thermopile　is　0.010121μV/(W/m2).　Steady-state　tests　of　the　thermopile　and　the　thermocouple　were　taken　separately.　Time　constant　of　the　thermocouple　is　about　0.26s,　which　is　faster　the　thermopile　of　1.57s.　©　(2014)　Trans　Tech　Publications,　Switzerland.
