Carbon fibre can store energy in the body of a vehicle

Carbon fibre can store energy in the body of a vehicle

Press Releases   •   Oct 18, 2018 07:00 BST

A study has shown that carbon fibres can work as battery electrodes, storing energy directly. This opens up new opportunities for structural batteries, where the carbon fibre becomes part of the energy system. The use of this type of multifunctional material can contribute to a significant weight-reduction in the aircraft and vehicles of the future – a key challenge for electrification.

New innovation improves the diagnosis of dizziness

Press Releases   •   Sep 10, 2018 07:01 BST

Half of over-65s suffer from dizziness and problems with balance. But some tests to identify the causes of such problems are painful and can risk hearing damage. Now, researchers from Chalmers University of Technology, Sweden, have developed a new testing device using bone conduction technology, that offers significant advantages over the current tests.

Fibre-optic transmission of 4000 km made possible by ultra-low-noise optical amplifiers

Fibre-optic transmission of 4000 km made possible by ultra-low-noise optical amplifiers

Press Releases   •   Jul 05, 2018 07:00 BST

​Researchers from Chalmers University of Technology, Sweden, and Tallinn University of Technology, Estonia, have demonstrated a 4000 kilometre fibre-optical transmission link using ultra low-noise, phase-sensitive optical amplifiers. This is a reach improvement of almost six times what is possible when using conventional optical amplifiers. The results are published in Nature Communications.

How smart technology gadgets can avoid speed limits

How smart technology gadgets can avoid speed limits

Press Releases   •   Jun 28, 2018 07:00 BST

​Speed limits apply not only to traffic. There are limitations on the control of light as well, in optical switches for internet traffic, for example. Physicists at Chalmers University of Technology now understand why it is not possible to increase the speed beyond a certain limit – and know the circumstances in which it is best to opt for a different route.
