Traditional coating or printing conductive layers are prone to detachment under repeated application, removal, and skin sweat infiltration. Advanced Institute Technology adopts online plasma activation combined with low-temperature gradient magnetron sputtering technology to effectively improve the bonding strength between the substrate and the metal layer by bombarding the substrate surface with plasma. The metal coating achieves stress transition from the substrate to the metal layer through gradient coating design, effectively avoiding interface delamination caused by modulus differences. The adhesion force of the coating reaches 5B level, with a peel strength exceeding 0.8 N/mm. It can withstand hundreds of thousands of dynamic bending and multiple uses, and the electrode impedance has no significant drift.

By precisely controlling the coating thickness (continuously adjustable from nanometer to micrometer level) and microstructure, the product exhibits extremely low and stable electrode skin contact impedance in the frequency range of 10Hz-10kHz. Low impedance means higher signal-to-noise ratio and more accurate signal acquisition, which can significantly reduce common mode interference and motion artifacts, improve the quality of weak bioelectric signal acquisition, especially suitable for dynamic electrocardiogram monitoring, brain computer interface, and precise neural regulation.

The conductive coating is made of metal materials that have undergone biological safety evaluation. The full vacuum dry process eliminates chemical solvent residues, and the finished product meets the ISO 10993 and GB/T 16886 series biocompatibility standards. For high humidity and sweat environments, the chemical inertness of gold endows the coating with excellent corrosion resistance, making it suitable for long-term wearing scenarios. The product supports continuous monitoring of various bodily fluids such as sweat.

In addition to standard Ag/AgCl electrodes, Advanced Institute Technology can also provide solutions such as titanium plating, gold plating, platinum plating, copper plating, nickel plating, as well as carbon based and conductive polymer coatings such as carbon nanotubes, graphene, PEDOT: PSS, to meet cutting-edge requirements such as dry electrodes, capacitive electrodes, and microneedle array electrodes. Titanium layer can be used for flexible dry electrodes, combining conductivity and biological inertness; Gold plating is suitable for high-precision EEG recording; Graphic technology can manufacture multi-channel electrode arrays, supporting customer differentiated design. The company has mastered the full chain process from surface activation, vacuum coating, to metal coating, and can customize the coating system and microstructure of electrode materials according to different application needs.

The company is equipped with a high-precision roll to roll vacuum coating production line, which adopts composite processes such as magnetron sputtering and vacuum evaporation. It can process flexible substrates with a width of up to 600mm, with controllable low temperature throughout the process and online spectral monitoring of film thickness. The resistance fluctuation of the entire roll is controlled within ± 5%, meeting the stable supply of large quantities of medical grade electrode sheets. The company has introduced electromagnetic heating roller technology to achieve continuous roll to roll production, with a temperature difference controlled within ± 1 ℃, significantly improving product adhesion and structural stability. At the same time, it provides back-end manufacturing services such as slicing, laminating, conductive gel coating, etc. to help customers shorten the supply chain.
