EPFL discovery brings us closer to next-generation electronics

EPFL engineers have found a way to control the interactions between excitons – quasiparticles that may one day transport data and replace the electrons in electronic devices. The engineers’ method involves applying an electric field to a two-dimensional (2D) semiconducting material.

Cryo-imaging lifts the lid on fuel cell catalyst layers

Thanks to a novel combination of cryogenic transmission electron tomography and deep learning, EPFL researchers have provided a first look at the nanostructure of platinum catalyst layers, revealing how they could be optimized for fuel cell efficiency.

How to make self-folding surgical tools

For minimally invasive surgery, the instruments used must be small. ETH Zurich researchers have now developed a method to transport large devices through a narrow catheter. This expands the possibilities for designing minimally invasive surgical tools.

Thread-like pumps can be woven into clothes

EPFL researchers have developed fiber-like pumps that allow high-pressure fluidic circuits to be woven into textiles without an external pump. Soft supportive exoskeletons, thermoregulatory clothing, and immersive haptics can therefore be powered from pumps sewn into the fabric of the devices themselves.

Learning to “sell” a prototype designed in just a few weeks

For the last four years at EPFL, a Master’s course jointly run by the College of Management of Technology and the School of Engineering has been winning over students seeking a course that meets the needs of local industry.

3D-printed insoles measure sole pressure directly in the shoe

ETH Zurich Empa

Researchers at ETH Zurich, Empa and EPFL are developing a 3D-printed insole with integrated sensors that allows the pressure of the sole to be measured in the shoe and thus during any activity. This helps athletes or patients to determine performance and therapy progress.
