Abstract

Conventional rigid metals and alloys are characterized by complex processing and high cost due to their high hardness and high melting point. Low-melting-point alloy has the advantages of easy processing and high conductivity due to its low melting point, which is very suitable for application in sensor electrodes. In this study, InSnBi electrode with a serpentine structure was fabricated by microfluidic technology. We simulated and compared electrodes with different structures, and studied the influence of manufacturing process on electrode performance. It was found that the interface of metal hydrogel was closely linked. And the InSnBi alloy was shown with good biocompatibility. The fabricated electrode has the potential to be applied for continuous glucose sensing.
