Surface Temperature Measurements in Microscale with Temperature Sensitive Fluorescence
온도 민감 형광을 이용한 마이크로 스케일 표면온도 측정
Abstract
The effects of substrate material on the local heating performance of microheaters are studied by both numerical analysis and experiment. Transient conduction analysis shows that the substrate material with low thermal conductivity is critical to the local heating and fast response. A measurement technique for surface temperature field in microscale is newly proposed, which uses temperature sensitive fluorescent dye coated on the surface. The measured surface temperature fields on microheater arrays fabricated on different substrates are presented.
