Abstract

This paper presents a new design of silicon-based microfluidic thermal biosensor made by dual thermopiles and a microfluidic channel introducing a splitting and mixing of sample flow. Each thermopile consists of 26 Cr/Cu thermocouple pairs and electrodes of 50-wm width. The Seebeck coefficient's difference of each thermocouple is 19.97-µV/K, and the total sensitivity of thermopile is 519.22-µV/K. This dual-thermopile system enables the thermal biosensor to obtain reliable measurement data since it detects biochemical reaction and reference temperature simultaneously.
