Digital twins are computer-based models of an object or even a human organ, and the technology behind them is advancing at a rapid pace. EPFL will host a series of talks and seminars on this topic at its Digital Twin Days on 15 and 16 November. An ideal opportunity to learn more about the work EPFL researchers are doing in this pioneering field.

An international collaboration led by EPFL chemical engineers has overcome a problem in the manufacturing of perovskites that reduces their efficiency as solar panels. The approach produced perovskite solar panels with an efficiency of 23.9% and operational stability longer than 1000 hours.

By combining two microscopy methods, EPFL researchers are able to see what is happening inside a cell and on its membrane simultaneously, giving unprecedented insight into the cellular processes that occur during infection, for example.

Thanks to the enhanced light-field technology developed by EPFL spin-off Creal, augmented-reality and virtual-reality images appear increasingly life-like with less strain on users’ eyes. The company will present the latest version of its system at the Augmented World Expo this week in California.

Changing temperatures and varying winds over the seasons cause great fluctuations in Lake Geneva. The LéXPLORE research platform monitored the movement of water within the lake for a year to learn more about how natural factors influence the lake’s mixing. The resulting analysis now paints a fuller picture of mixing in large lakes, which had previously only been studied over shorter time periods.
