Dielectric Ceramic Materials for MLCC Miniaturization
An analysis of 80 patents and publications (2005–2023) reveals a parallel technology trajectory where printed 2D dielectrics—particularly hexagonal boron nitride—are emerging as candidates for miniaturized capacitor structures alongside electrohydrodynamic printing advances.
80 Patents and Publications Mapping a Parallel Technology Path
The dataset comprises 80 patents and academic publications spanning from 2005 to 2023, focusing predominantly on printed electronics technologies, functional ink formulations, and advanced material systems. While the dataset does not contain patents specifically directed at traditional barium titanate-based MLCC dielectrics, it reveals a parallel technology trajectory where printed dielectric materials are emerging as candidates for miniaturized capacitor structures.
The dominant assignees include Vorbeck Materials Corporation (with numerous graphene-based printed electronics patents), Guangzhou Chinaray Optoelectronic Materials Ltd. (functional ink formulations), and various academic institutions researching sustainable and high-performance printable materials. The technical approaches cluster around inkjet printing, screen printing, and electrohydrodynamic jet printing for depositing functional dielectric and conductive layers at increasingly fine resolutions. Standards bodies such as IEC and IEEE continue to shape qualification criteria for emerging dielectric materials.
The 2D material dielectric approach—particularly hexagonal boron nitride (h-BN)—represents a significant departure from conventional ceramic processing, offering potential advantages in deposition uniformity and substrate compatibility that are relevant to the advanced materials landscape for 2026 MLCC design.

Hexagonal Boron Nitride and Emerging Printable Dielectrics
Research from 2017–2022 validates h-BN as a printable dielectric for capacitor structures, while identifying formulation gaps for TMDs and black phosphorus.
Fully Inkjet-Printed 2D-Material Heterojunctions
Fully inkjet-printed 2D-material active heterostructures using graphene and h-BN inks enabled field-effect transistors that operate at room temperature, under strain, and after washing cycles—demonstrating the robustness required for practical applications. This work established the foundational feasibility of 2D dielectric inks in real-world conditions relevant to IP analytics for electronics innovation.
Graphene + h-BN heterostructureAll-2D Material Inkjet-Printed Capacitors
Water-based and biocompatible graphene and h-BN inks were used to fabricate all-2D material inkjet-printed capacitors achieving an areal capacitance of 2.0 ± 0.3 nF cm⁻² for a dielectric thickness of approximately 3 μm, with negligible leakage currents. The derived dielectric constant of 6.1 ± 1.7 positions this approach as viable for integrated circuit applications where traditional ceramic dielectrics face manufacturing constraints.

Main building blocks for digital electronics have been obtained using MoS₂, h-BN, and carbon nanotubes through inkjet printing, achieving performance comparable to mainstream organic technology. This work, published in 2021, validates manufacturing viability for printed low-dimensional material circuits on flexible substrates—a key consideration for next-generation MLCC integration strategies tracked through materials intelligence platforms.
MoS₂ + h-BN + CNT circuitsInk Formulation Gaps for TMDs and Black Phosphorus
While printed graphene-based devices are transitioning from laboratory applications toward mass-producible systems, a similarly clear picture does not yet exist for h-BN, transition metal dichalcogenides (TMDs), and black phosphorus. This formulation gap, identified in a 2022 review, represents both a challenge and an opportunity for dielectric material development targeting 2026 applications. External research bodies including NIST are advancing characterisation standards for these materials.

Key Players and Innovation Concentration
The patent landscape reveals clear concentration among a few key players, with Vorbeck Materials Corporation holding foundational IP across multiple jurisdictions from 2009 through 2020.
Vorbeck Materials Corporation
Dominates with at least 15 patent filings covering graphene-based conductive inks and printed electronic devices. Active patents maintained across US, EP, WO, and IN jurisdictions through 2020. Their foundational technology involves functionalized graphene sheets combined with polymeric binders, consistently described across their portfolio spanning 2009–2020.

Bio-Based and Sustainable Ink Formulations for Printed Electronics
The printed electronics field is increasingly emphasising sustainable materials, which may influence MLCC manufacturing approaches. A 2023 review surveys biodegradable systems using naturally produced materials, noting that to produce sustainable inks, most materials used in formulation should be biobased, biodegradable, or not considered critical raw materials. This aligns with broader EU critical raw materials policy tracked by bodies such as ECHA.
A 2020 study demonstrates how cellulose and lignin-based inks can be patterned using screen printing followed by laser graphitization, achieving a sheet resistance of 3.8 Ω/sq and high graphitization degrees. This forest-based approach opens possibilities for sustainable electronics manufacturing that could reduce reliance on critical minerals in MLCC electrode layers.
Environmental considerations extend to substrate materials, with research addressing the challenge of replacing plastic substrates with biodegradable shellac-paper composites while maintaining printability and electrical performance. Organisations such as EPA and the PatSnap chemicals solutions team track regulatory implications for such material transitions.
- Materials must be biobased or biodegradable
- No critical raw materials in formulation
- Compatible with existing printing processes
