Rethinking What Printed Electronics Can Be Made Of

At PDoT.tech, we’ve spent considerable time asking a deceptively simple question: what if the inks powering the next generation of flexible electronics didn’t rely on metals, toxic solvents, or complex processing?

The answer is taking shape in our lab — and we’re excited to share it.

We’ve developed a platform of p- and n-type highly conductive, water-based carbon pastes using bio-based dispersants, purpose-built for screen printing. The result? Patterned films with outstanding adhesion, consistent electronic performance, and real compatibility with the substrates that matter most — paper, plastics, and textiles.

What sets these formulations apart:

• High solid loading with stable rheology — engineered to perform reliably on industrial screen-printing equipment
• Low sheet resistance after simple, low-temperature drying — no energy-intensive curing, no exotic equipment
• Roll-to-roll readiness — designed from the ground up for scalable, continuous manufacturing

This isn’t just a materials story. It’s a pathway toward metal-free, cost-effective, and genuinely sustainable flexible electronics — from electrodes and distributed sensors to energy harvesters and electrothermal heaters.

We believe the industry is ready for inks that perform at a high level without the environmental and supply-chain baggage of conventional approaches. This platform is our contribution to making that shift practical.

We’re actively looking for partners interested in process optimization, device integration, and pilot-scale validation. If that’s your space, we’d love to talk.
