Plastic electronics for light diodes and prostheses

29.04.2002


Is it possible to make components out of organic polymers (plastics) whose structure is such that severed nerves can grow right into them and connect with electrodes in a prosthetic hand, for example? This is one of the research fields for Tobias Nyberg at the Section for Biomolecular and Organic Electronics at Linköping University, Sweden.



Part of Tobias Nyberg’s dissertation is based on collaboration with cell biologist Helena Jerregård. Her task is to find ways to get tangled nerves to sort themselves out into nerve threads and tactile threads respectively. Tobias Nyberg’s job is to produce the structures in which the sorted nerves can connect with the electrodes from a future prosthesis. The materials he has used are plastics etched with patterns of tiny channels 20 millionths of a meter in size, covered both by an electrically conductive polymer and a protein that the nerves can grow on.

Another section of the dissertation treats nano- and micrometer-sized structures for solar cells and light diodes. In these contexts it is important that as much light as possible be absorbed by the material, despite the fact that, for other reasons, the material should also be a thin as possible. Tobias Nyberg has therefore found a way to create light-refracting patterns less than a thousandth of a millimeter in size, patterns that prevent light from going straight through, bending it instead so that more light is absorbed.


The Linköping researcher has also invented and applied for a patent for a method to make “micro-domes” of water. His point of departure is a surface that is patterned in circles, where the circles are made of a water-friendly material whereas the surrounding surface is made of a water-repellent material. If such a surface is exposed to cold, moisture in the air condenses on the water-friendly circles, building tiny bumps. This pattern in turn can be molded out of a polymer material with possible future applications in camera apertures, light diodes, and solar cells.

Im Focus: Neutron star merger directly observed for the first time

University of Maryland researchers contribute to historic detection of gravitational waves and light created by event

On August 17, 2017, at 12:41:04 UTC, scientists made the first direct observation of a merger between two neutron stars--the dense, collapsed cores that remain...

Im Focus: Breaking: the first light from two neutron stars merging

Seven new papers describe the first-ever detection of light from a gravitational wave source. The event, caused by two neutron stars colliding and merging together, was dubbed GW170817 because it sent ripples through space-time that reached Earth on 2017 August 17. Around the world, hundreds of excited astronomers mobilized quickly and were able to observe the event using numerous telescopes, providing a wealth of new data.

Previous detections of gravitational waves have all involved the merger of two black holes, a feat that won the 2017 Nobel Prize in Physics earlier this month....

Im Focus: Smart sensors for efficient processes

Material defects in end products can quickly result in failures in many areas of industry, and have a massive impact on the safe use of their products. This is why, in the field of quality assurance, intelligent, nondestructive sensor systems play a key role. They allow testing components and parts in a rapid and cost-efficient manner without destroying the actual product or changing its surface. Experts from the Fraunhofer IZFP in Saarbrücken will be presenting two exhibits at the Blechexpo in Stuttgart from 7–10 November 2017 that allow fast, reliable, and automated characterization of materials and detection of defects (Hall 5, Booth 5306).

When quality testing uses time-consuming destructive test methods, it can result in enormous costs due to damaging or destroying the products. And given that...
