Q&A: 3D-Printed Hydrogel Blocks Can Aid Robotics and Diagnostics

  • Magazine Article
  • TBMG-34631
Published 2019-06-01 by Tech Briefs Media Group in United States

Ian Y. Wong, Ph.D., is Assistant Professor of Engineering, Molecular Pharmacology, Physiology and Biotechnology at Brown University in Providence, RI. He and colleagues have developed a new type of hydrogel blocks that can be assembled like LEGO®s.

 

Encapsulated Nanoparticles Offer Promise for Biomedical Applications

  • TBMG-34441
Published 2019-05-01 by Tech Briefs Media Group in United States

The Polymerization Process Research Group of the Polymat Institute of the UPV/EHU–University of the Basque Country has efficiently encapsulated semiconductor nanocrystals or quantum dots of various sizes into polymer particles. Great stability in terms of their optical properties and good fluorescence control when combining different quantum dots have been achieved. The possible applicability of these materials as sensors of volatile organic compounds has also been explored.

Published 2019-05-01 by Tech Briefs Media Group in United States

Scientists have taken inspiration from underwater invertebrates like jellyfish to create an electronic skin with similar functionality. Like a jellyfish, the electronic skin is transparent, stretchable, touch-sensitive, and self-healing in aquatic environments.

 

Bendable Electronic Paper Displays a Range of Colors

Published 2019-05-01 by Tech Briefs Media Group in United States

The combination of conductive polymers on nanostructures was demonstrated as suited to creating electronic displays as thin as paper. The “paper” is similar to the Kindle tablet. It does not light up like a standard display, but rather reflects the external light that illuminates it; therefore, it works very well where there is bright light such as sunlight, in contrast to standard LED displays that work best in darkness. At the same time, it needs only a tenth of the energy that a Kindle tablet uses, which itself uses much less energy than a tablet LED display.

 

3D Printer Uses Rays of Light to Shape Objects

  • TBMG-34388
Published 2019-05-01 by Tech Briefs Media Group in United States

Most 3D printers, including light-based techniques, build up 3D objects layer by layer. This leads to a “stair-step” effect along the edges. They also have difficulties creating flexible objects because bendable materials could deform during the printing process, and supports are required to print objects of certain shapes, like arches.

 

Tiny Optical Elements Could One Day Replace Traditional Refractive Lenses

A Northwestern University research team has developed tiny optical elements from metal nanoparticles and a polymer that one day could replace traditional refractive lenses to realize portable imaging systems and optoelectronic devices. The flat and versatile lens, a type of metalens, has a thickness 100 times smaller than the width of a human hair.
