Printed Electronics Materials Landscape 2026 — PatSnap Eureka
Printed Electronics Materials: Graphene Inks, 2D Materials & Sustainable Substrates
An analysis of 78 patents and literature records reveals that functionalized graphene sheets, multi-method printing fabrication, and sustainable substrates are the dominant innovation vectors in printed electronics — with Vorbeck Materials Corporation, Guangzhou Chinaray, and DST Innovations leading the field.
Graphene-Based Conductive Inks Dominate the Printed Electronics Patent Landscape
The 78-document dataset reveals significant innovation in electrically conductive inks utilizing functionalized graphene sheets. Multiple patents from Vorbeck Materials Corporation describe printed electronic devices comprising substrates with applied layers of electrically conductive ink containing functionalized graphene sheets and binders, with filings spanning 2013 through 2018.
Research literature further supports graphene ink development: a 2018 study published via PatSnap Eureka demonstrated environmentally sustainable production routes achieving conductivities of 7.13 × 10⁴ S m⁻¹ using non-toxic solvents — a milestone for sustainable wireless connectivity and IoT applications. This places graphene inks among the most electrically capable solution-processed materials available.
Beyond graphene, the dataset highlights emerging 2D materials including MoS₂ and hexagonal boron nitride, which are enabling fully inkjet-printed field-effect transistors for wearable and textile electronics, as described in 2017 research on two-dimensional material field-effect heterojunctions. These developments are tracked across databases such as PatSnap Analytics for competitive intelligence purposes.
The sustainability dimension is increasingly prominent: a 2023 review on sustainable inks catalogues materials for conductive, dielectric, and piezoelectric applications, emphasising bio-based substrates and green solvents as key directions for the field. Organisations such as OECD have also flagged sustainable electronics manufacturing as a policy priority.
Five Printing Methodologies Underpin Electronics Fabrication Innovation
According to Vorbeck Materials Corporation patents from 2018, the dataset covers a broad range of deposition techniques — each suited to different substrate types and resolution requirements.
Inkjet & Electrohydrodynamic Printing
Inkjet printing enables high-resolution, drop-on-demand deposition of functional inks onto flexible substrates. Electrohydrodynamic printing extends resolution further, enabling sub-micron feature sizes. Both are documented in Vorbeck Materials Corporation patents (2018) and underpin fully inkjet-printed 2D material field-effect heterojunctions for wearable electronics (2017). PatSnap Analytics tracks filing velocity across these methods.
Wearable electronicsScreen, Gravure & Flexographic Printing
Screen printing delivers thick, high-conductivity traces suited to large-area electronics. Gravure and flexographic printing are adapted for roll-to-roll production at scale. All three methods are listed in Vorbeck Materials Corporation’s 2018 patent portfolio as applicable deposition techniques for graphene-based functional inks. Industry bodies such as IEEE have published standards covering printed electronics fabrication.
Roll-to-roll scalableMolecular Ink Deposition — Silver & Copper Formulations
Her Majesty the Queen in Right of Canada (Communications Research Centre) developed molecular ink-based printed electronics using silver carboxylate and copper formate formulations, as described in a 2019 patent. These metal-organic decomposition inks sinter at low temperatures, making them compatible with paper and polymer substrates. Research on these formulations is accessible via PatSnap Chemicals.
Low-temperature sinteringOptoelectronic Printing Formulations for OLED Devices
Guangzhou Chinaray Optoelectronic Materials Ltd. focuses on printing compositions for OLED and optoelectronic devices, with a 2023 patent covering functional material thin film preparation. DST Innovations Limited similarly targets printable functional materials for OLEDs and organic photovoltaics (2016). Both assignees contribute to a growing body of work on solution-processed light-emitting and photovoltaic layers. Organisations such as NREL track photovoltaic efficiency benchmarks.
