Vorbeck Materials CorporationSilver Carboxylate & Copper Formate Formulations
Patents from Her Majesty the Queen in Right of Canada (jointly with E2IP Technologies Inc.) describe flake-less printable compositions containing 30–60 wt% silver carboxylate with polymeric binders, which can be sintered to form conductive traces. Alternative copper-based formulations using bis(2-ethyl-1-hexylamine) copper(II) formate compounds offer cost-effective options for printed biosensor electrodes. Pending applications span European, Canadian, and Indian jurisdictions.
30–60 wt% silver carboxylateGraphene-Silver Composite Inks on Textiles
All inkjet-printed graphene-silver composite inks on textiles address limitations of pure graphene inks regarding concentration stability while reducing the silver loading needed compared to pure metal inks. This balanced performance-cost profile is particularly suitable for wearable biosensor manufacturing. The composite approach was validated for highly conductive wearable electronics applications in 2019 research.
Balanced performance-cost profileGraphene & hBN Inkjet-Printed Field-Effect Transistors
Fully inkjet-printed heterostructures using graphene and hexagonal boron nitride inks fabricate flexible, washable field-effect transistors on textiles. This capability to maintain functionality through washing cycles is critical for practical wearable biosensor deployment, as demonstrated in 2017 research on two-dimensional material field-effect heterojunctions for wearable and textile electronics.
Wash-resistant performancePrinting Technologies for Hydrogel-Integrated Biosensor Fabrication
The manufacturing pathway for hydrogel-based wearable biosensors increasingly leverages additive printing technologies. Electrohydrodynamic (EHD) jet printing has emerged as a particularly promising technique for high-resolution patterning, enabling direct deposition of functional materials with resolution capabilities exceeding conventional inkjet methods — making it suitable for biosensor electrode geometries requiring micron-scale features, as surveyed in a 2021 review on EHD printing for practical printed electronics.
Inkjet printing remains the most widely investigated technique due to its digital design flexibility and compatibility with diverse substrates. Printing parameters including dot spacing and sintering conditions directly influence device performance in biosensor electrode fabrication. For scaled manufacturing, screen printing offers advantages in throughput and ink volume capacity. Water-based graphene inks suitable for screen printing have achieved conductivities of 7.13 × 10⁴ S/m, supporting fabrication of wireless antennas operating from MHz to tens of GHz frequencies — enabling data communication and energy harvesting for autonomous wearable biosensor systems.
Three-dimensional printing approaches are expanding the design space for biosensor architectures. Research from Sichuan University (2022) describes self-healing functional inks that eliminate interface resistance between printed layers while providing electrical, magnetic, and electrochemical properties applicable to energy storage, electromagnetic shielding, and stress sensing in wearable devices.
