Fully Recyclable Printed Electronics | Printed Electronics World

Engineers at Duke University have developed the world s first fully recyclable printed electronics. By demonstrating a crucial and relatively complex computer component the transistor created with three carbon-based inks, the researchers hope to inspire a new generation of recyclable electronics to help fight the growing global epidemic of electronic waste. The work appears online April 26 in the journal Nature Electronics.   Silicon-based computer components are probably never going away, and we don t expect easily recyclable electronics like ours to replace the technology and devices that are already widely used, said Aaron Franklin, the Addy Professor of Electrical and Computer Engineering at Duke.

Particle-Free Conductive Inks as an Advantageous Alternative, IDTechEx Explores

Share this article Share this article BOSTON, March 8, 2021 /PRNewswire/ Conductive inks are a long-established technology, with silver flake-based inks used extensively in multiple industries, including solar panels and glucose test strips. However, technology rarely stands still, and there is extensive innovation within the conductive ink space. Particle-free inks are an especially promising example with multiple advantages and applications.

Right – flexible printed electronics, iStock (PRNewsfoto/IDTechEx) In a particle-free ink, a solvated metal salt is reduced in-situ to produce a metal. In complete contrast to more conventional conductive inks, this means that the uncured particle-free ink is often transparent. The chemical reaction is induced by heat, light or plasma, and

Silver Price Volatility Could Affect Conductive Ink Composition, Says IDTechEx

Silver Price Volatility Could Affect Conductive Ink Composition, Says IDTechEx News provided by Share this article Share this article BOSTON, Feb. 2, 2021 /PRNewswire/  The remarkable price increases in particular US stocks, most notably GameStop, made the news last week as the power of retail investors to move markets became clear. On Monday 1 st Feb, the BBC reported that silver prices increased by around 10% as retail investors turned their attention to commodities, reaching a 5-month high of almost $950/kg. While silver has many uses, such as mirrors and jewelry, conductive ink is a significant application with a market estimated by IDTechEx at around $2.3bn annually. By far the most common use for silver ink is in the conductive fingers and busbars onto solar panels, making silver ink an essential component in the adoption of renewable energy sources. Additionally, silver ink is used across the entire range of printed electronics technologies, such as printed pressure se
