LI Juan, ZHANG Congchun, YANG Shenyong, et al. Research and fabrication of MEMS thin-film heat flux sensor[J]. 2019, (5): 71-73. DOI: 10.13873/J.1000-9787(2019)05-0071-03.
a micro-electro-mechanical system( MEMS) thin-film thermopile( TFTP) heat flux senor is designed and fabricated. The property of TFTPs with different structure is modeled and analyzed by FEA COMSOL in order to obtain the best sensor performance with a smaller device dimensions. The MEMS TFTPs are proposed and manufactured based on the optimized design. The testing system has been built to characterize the performance of fabricated TFTPs. It can be found that the output voltage responses are consistent with simulation results when a step heat flux applied. The test results also show that the output voltage of TFTPs responded linearly with heat flux.
