Electrical and electronic engineering

It is not easy to make batteries cheap, efficient, durable, safe and environmentally friendly at the same time. Researchers at ETH Zurich have now succeeded in uniting all of these characteristics in zinc metal batteries.

ETH students have developed sensors that can indicate how people use urban spaces. They anonymously measure how people use objects such as chairs in a public square. The sensors have proven useful in the test run and could be used in future to plan public spaces based on needs.

A study by researchers at ETH Zurich shows for the first time how a relaxation of Swiss spatial planning policy would affect the locations of wind turbines. If the aim is to have as few wind turbines as possible in the Alps and in Switzerland in general, it would be worth considering using windy agricultural areas on the western Swiss Plateau.

Mental health disorders can only be diagnosed on the basis of symptoms – and individual outcomes cannot be accurately predicted. An ETH scientist hopes to change that with the help of mathematical models.

EPFL researchers have come up with a new approach to electronics that involves engineering metastructures at the sub-wavelength scale. It could launch the next generation of ultra-fast devices for exchanging massive amounts of data, with applications in 6G communications and beyond.

Electronic components are becoming smaller, more complex and more powerful – this calls for new solutions for joining them. An Empa team is developing nanostructured joining materials for the next generation of microelectronics and other demanding applications.
