Piezoresistive vs Resistive Inks: What’s the Difference?


In the world of printed electronics and smart surfaces, the type of ink you choose defines what your device can sense; or whether it can sense at all.


- Resistive Inks

These inks have a fixed resistance, unaffected by pressure or deformation. They’re perfect for applications like printed resistors, heater circuits, and touch buttons — where stability matters more than sensitivity.


✅ Simple, low-cost

❌ No sensing capability


- Piezoresistive Inks

These advanced materials change resistance when stretched or pressed, turning mechanical force into an electrical signal.


✅ Ideal for wearable sensors, smart textiles, soft robotics

✅ Sensitive to subtle force/stress changes

✅ Better durability, linear response


Why it matters:

Traditional Force Sensing Resistors(FSRs) using carbon resistive inks rely on contact area changes meaning performance can degrade, and readings may be inconsistent.

In contrast, Nanopaint’s Piezoresistive Inks senses force intrinsically with direct, smooth, and repeatable responses.


Bottom Line:

Resistive inks conduct.

Piezoresistive inks sense.


And with #Nanopaint's Piezoresistive #Inks, the ink is the sensor enabling ultra-thin, fully printed, and flexible sensing surfaces for next-gen applications.

Envalior launches new PPS compounding facility in Uerdingen, Germany. New facility supports growing demand for Xytron™ in Europe and the Americas. To better serve growing customer demand in Europe and the Americas, Envalior – a global leader in sustainable and high-performance engineering materials – announces that it will invest in a PPS (Polyphenylene Sulfide) compounding facility in Europe. Envalior’s PPS material Xytron™ combines a strong set of properties, including excellent chemical and hydrolysis resistance at elevated temperatures, extremely stable heat aging performance up to 240°C, very good and stable electrical properties at elevated temperatures, low moisture absorption with high dimensional stability, and inherent flame retardance that meets UL94 V0.  Since 2016, when Xytron™ entered the market, the PPS material has built a strong track record across OEMs and tier customers. The new facility will provide local supply and additional services to customers in Europe whi...

Today's KNOWLEDGE Share : What Is Going Wrong in UK Plastics Recycling?

Today's KNOWLEDGE Share What Is Going Wrong in UK Plastics Recycling? Biffa shut its Sunderland plant. Viridor walked away from Avonmouth and Rochester. Yes Recycling Fife collapsed within a year. All three were backed by major investments All three had buyers lined up for recyclate All three are now offline This is not bad luck It is bad structure Over the next four posts I will break down: 1. Why cheap virgin imports are undercutting UK recyclers 2. How weak policy enforcement is fuelling market failure 3. What volatile PRNs and cheap exports are doing to infrastructure 4. Why demand from brands is softer than their promises Let’s start with the first: **Cheap Virgin Resin = Broken Economics** Virgin PE, PP, and PET have been flooding the global market. New capacity in Asia and the US has driven prices down 30 to 40 percent. Meanwhile, recycled plastic costs more to produce in the UK than it can sell for. We are asking UK recyclers to compete with materials made in places with – ...

Today's KNOWLEDGE Share “Robotic 3D printing can compete with traditional boatbuilding”, Simone Barbera and Mattia De Santis, Caracol V2 catamaran was printed in Italy at Caracol’s production center and headquarter in Barlassina, near Milan, with a Heron AM 400, Caracol’s robotic Large Format Additive Manufacturing (LFAM) platform. The lattest was specifically configured with a 7-axis robotic arm mounted on a rail, enabling the printing of parts up to 10 meters in length. How did the collaboration between V2 Group and Caracol come about? Simone Barbera : The collaboration between V2 Group and Caracol originated from a shared vision to revolutionize boat manufacturing through sustainable innovation. V2 Group, a Spanish-company specialized in nautical design and engineering, is seeking to develop electric vessels manufactured sustainably. On the other hand, Caracol, leader in robotic advanced manufacturing technology, had had years of experience working with Large Format Additive Ma...
