Conductive inks for printed electronics.

Silver and graphene BeeInk, plus functional, assembly and battery materials, ready to print with Direct Ink Writing.

GOOD TO KNOW

Conductivity comes from the material you print. Silver, graphene and carbon each conduct differently, so the right ink depends on the application you want to build.

HOW CONDUCTIVE INKS WORK

How a line of ink starts to conduct.

A conductive ink is a liquid full of tiny conductive particles. While the ink is wet, the particles float apart and no current can pass. Curing brings them together into one continuous path.

WET INKParticles apartRight after printing, particles are spread through the liquid. The line does not conduct yet.
CURINGSolvent leavesHeat drives out the solvent. The line shrinks and the particles move closer together.
CURED TRACKA connected networkParticles come close enough to connect. Current passes through their contacts and, in nanoparticle inks, by tunnelling across the tiny gaps between them.
WHAT A PRINTED INK CAN DO
Conduct
Tracks, pads, electrodes and antennas.
Heat
Controlled resistance turns current into even warmth.
Sense
Resistance that changes with strain, touch or chemistry.
Insulate
Separates layers so one track can cross another.
Store energy
Printed electrodes for batteries and supercapacitors.
DEVELOPED BY BEESPENSER

BeeInk.

Functional inks, developed for what comes next.

Beespenser's own conductive inks, developed for syringe-based Direct Ink Writing and tuned to Monobee's Dispensing Module for stable, repeatable lines.

BEEINK · SILVER

BeeInk Flake Silver

Prints highly conductive tracks, pads and busbars. Flake-shaped silver particles overlap like tiles, giving low resistance after curing.

BEEINK · GRAPHENE

BeeInk Graphene

Conducts with a useful, higher resistance. The printed line itself becomes the sensing or electrochemical element.

From conductive traces to functional layers and electronic assembly, explore material technologies that enable the development of printed and flexible electronics.

MATERIALWHAT IT DOESUSED INDATA SHEET
CONDUCTIVE INK

Anode Ink

Zinc-based negative electrode of a printed battery. Releases electrons while the battery discharges.

CONDUCTIVE INK

Cathode Ink

Manganese dioxide-based positive electrode of a printed battery, on the other side of the cell.

FUNCTIONAL LAYER

Electrolyte Ink

A printable battery electrolyte that lets ions, not electrons, move between the two electrodes.

FUNCTIONAL LAYER

Separator Ink

Insulating battery layer that keeps anode and cathode apart while letting ions pass.

FUNCTIONAL LAYER

Sealing Ink

Closes a printed battery cell, keeps the electrolyte in and protects it from the air.
