Current barriers to adoption
Traditional electronics rely on PCBs, with components from multiple suppliers assembled by specialists. Printed Electronics often follows the same fragmented model, with parts from disparate vendors and outsourced assembly.
The true potential lies in printing all functional components directly onto one substrate.
Printers need a complete suite of compatible functional inks to achieve this.
Current challenges: incompatible inks, lengthy trials, and heavy R&D — discouraging many printers from adoption.
Where Printing Meets Electronics
Printing technology is centuries old, highly advanced, and capable of fast, precise multilayer deposition. Electronics manufacturing, though younger, achieves nanometer-scale accuracy but at slower speeds.
Both industries rely on multilayer deposition, but with different goals.
Printed Electronics merges printing speed with electronic functionality — Saralon drives this convergence.

Stretchable Printed Electronics: New Advances in Functional Inks
Electronics are no longer made rigid; they’re printed, and just a soft touch away.
30/55
The same technology extends into wearables and smart textiles, where stretchability, comfort, and durability are critical.
Functional inks are central to this shift from rigid PCBs to flexible, stretchable electronics. We develop advanced inks to deliver simpler, more efficient, sustainable, and cost-effective solutions.
In industries like HMI, robotics, and automotive, users expect seamless, responsive controls integrated into surfaces. Flexible printed electronics (FPE) have enabled this, but stretchable switches and heaters go even further.
Unlike components that only bend, stretchable solutions conform to complex shapes, withstand repeated stress, and enable new designs — from heated steering wheels to curved touch controls.

New sets enable durability under stretching, bending, twisting, and thermoforming, with silver ink stretchable beyond 300%.
The Saral Inks Set simplifies this with full, application-specific ink sets for batteries, displays, heaters, and stretchable membrane switches.
Developing stretchable PE requires multiple compatible inks — silver, dielectric, polymer, graphene and carbon.
We design functional inks that evolve with the needs of the Printed Electronics industry. By staying flexible and responsive, we ensure reliable, future-ready solutions. Through close collaboration with partners, we refine and improve formulations to meet the real demands of modern electronics.
Stretchable heaters use Saral inks (silver, carbon, dielectric) for strong conductivity, protection, and reliability.
Options also include cost-effective low-silver inks and high-durability silver inks for fine line widths (~50 μm).

Pressure Sensitivity
The contacts on ACPAD are plated with real gold to make them pressure sensitive.
Pressure sensitivity is essential for the expressivity of the instruments played on ACPAD. To make pressure sensitive surfaces possible on such a thin device, the contacts of the pads are plated with gold (yes, actual gold). Thanks to this technology, ACPAD is only a few millimeters thick, but it can detect how hard you press the pads with remarkable precision!
