He has published more than 40 research papers, including 35 SCI papers, more than 20 SCI papers with IF 2 or above, holds 5 Japanese patents. He has presented more than 10 MEMS-related international conferences, including IEEE Transducers, Biosensors, IEEE NEMS, μTAS, etc.
Multi-functional thermal urine detection sensor chip project
The applicant innovatively proposed a urine sensor based on enzyme catalyzed reaction heat release and MEMS thermoelectric conversion detection mechanism on account of the signal interference problem existing in traditional electrochemical sensors in urine composition detection. A thermal sensor with high sensitivity was developed by regulating the energy band of monocrystalline silicon to achieve high Seebeck coefficient, which breaks through the constraints of traditional multi-electrode structure and PDMS microfluidic technology. It has the advantages of simple process, low cost, small device size and convenient mass production.
