Abstract: Microfluidics is a science of fluid mechanics involving micro-scale dimensions. The research in miniaturization of microfluidic devices and its use for microfluidic applications is increasing exponentially. The success of microfluidics owes to its inherent potential of influencing other fields such as chemical synthesis, biological analysis, optics, and information technology, etc. Various factors may affect the microfluidic behavior such as nature of microfluids, surface tension, contact angle, channel shape, temperature, viscosity, etc. The objective of this paper is to investigate the effect of temperature on microfluidic flow across a Cu–Mica microchannel. The microchannel was fabricated using a screen printing technique followed by substrate etching. Three different microfluids namely Ethanol, Methanol, and Chloroform were considered for investigations. The angle of elevation of the microchannel was maintained constant during all the investigations. The analysis of results showed that the flow rate of microfluids is temperature and fluid dependent.
