Engineers develop a soft, printable, metal-free electrode

Do an image search for "electronic implants," and you'll draw up a wide assortment of devices, from traditional pacemakers and cochlear implants to more futuristic brain and retinal microchips aimed at augmenting vision, ...

Hydrogel-based electrodes for brain implants developed

Hydrogels are physical and chemical polymer networks capable of retaining large quantities of liquid in aqueous conditions without losing their dimensional stability. They are used in a whole host of applications, and in ...

Making a transparent flexible material of silk and nanotubes

The silk fibers produced by Bombyx mori, the domestic silkworm, has been prized for millennia as a strong yet lightweight and luxurious material. Although synthetic polymers like nylon and polyester are less costly, they ...

This is what a stretchy circuit looks like

Researchers in China have made a new hybrid conductive material—part elastic polymer, part liquid metal—that can be bent and stretched at will. Circuits made with this material can take most two-dimensional shapes and ...

Polymer movement: key to next-generation coatings

Researchers in the Department of Materials Science and Engineering at Texas A&M University, led by doctoral student Victor Selin and Dr. Svetlana Sukhishvili, are making headway in understanding fundamental principles that ...

Biodegradable polymer coating for implants

Medical implants often carry surface substrates that release ac-tive substances or to which biomolecules or cells can adhere better. However, degradable gas-phase coatings for degradable implants, such as surgical suture ...

Accidental discovery may lead to improved polymers

Chemical Engineering Professor Tim Bender and Post-Doctoral Fellow Benoit Lessard's discovery of an unexpected side product of polymer synthesis could have implications for the manufacture of commercial polymers used in sealants, ...
