A soft robotic insect that survives being flattened by a fly swatter
Researchers at EPFL have developed an ultra-light robotic insect that uses its soft artificial muscles to move at 3 cm per second across different types of terrain. It can be folded or crushed and yet continue to move. Imagine swarms of robotic insects moving around us as they perform various tasks.

Excitons will shape the future of electronic devices
Excitons are quasiparticles made from the excited state of electrons and - according to research being carried out EPFL - have the potential to boost the energy efficiency of our everyday devices. It's a whole new way of thinking about electronics. Excitons - or quasiparticles formed when electrons absorb light - stand to revolutionize the building blocks of circuits.

River under current
Switzerland is proud of its strongly developed use of hydropower. This covers almost 60% of the country's electricity needs. The production of around 36 terawatt hours (TWh) per year is now to be increased by a further 3 TWh by 2050 as part of the energy strategy. Eawag, the water research institute, is today presenting internal and external experts at the Swiss Museum of Transport in Lucerne on the challenges this poses for water bodies and the approaches society can take to meet these challenges.

On-demand control of terahertz and infrared waves
Researchers from the University of Geneva and the University of Manchester have confirmed experimentally the theory of very strong magneto-optical resonance in graphene. The ability to control infrared and terahertz waves using magnetic or electric fields is one of the great challenges in physics that could revolutionise opto-electronics, telecommunications and medical diagnostics.

Using 60% less water in paper production
An EPFL researcher has developed a mathematical model for optimizing heat transfer in factories and dramatically reducing water and energy consumption. The model could, in theory, cut water use by 60% at a Canadian paper mill and allow the facility to produce as much as six times more power. Manufacturing consumer goods requires vast quantities of water, heat and electricity.

The holy grail of nanowire production
EPFL researchers have found a way to control and standardize the production of nanowires on silicon surfaces. This discovery could make it possible to grow nanowires on electronic platforms, with potential applications including the integration of nanolasers into electronic chips and improved energy conversion in solar panels.

EPFL researchers have developed a compact and efficient medium-frequency transformer. Their device is poised to enhance the flexibility and efficiency of tomorrow's smart grids and DC power distribution networks. An EPFL-made prototype has been thoroughly tested and presented in several tutorials designed for experts from the academic and industrial worlds.

Making the impossible possible
A new material for energy-efficient data storage reaches computer operating temperature Multiferroics are considered miraculous materials for future data storage - as long as their special properties can be preserved at computer operating temperatures. This task has now been accomplished by researchers at the Paul Scherrer Institute PSI, with colleagues from Institut Laue-Langevin ILL in Grenoble.

Tax incentives reduce energy consumption - if effectively implemented
By studying the effects of Basel's electricity levy, researchers at the University of Lucerne investigated how tax incentives work in practice and how their impact on energy consumption could be increased. The National Council and the Council of States decided not to debate the proposals of the Federal Council on the second phase of the Energy Strategy 2050 concerning the climate and energy tax incentive KELS.

Quantum chains in graphene nanoribbons
Researchers have achieved a breakthrough that could in future be used for precise nanotransistors or - in the distant future - possibly even quantum computers. A material that consists of atoms of a single element, but has completely different properties depending on the atomic arrangement - this may sound strange, but is actually reality with graphene nanoribbons.

Tracking cancer-cell development with "drinkable" electronic sensors
Thanks to an unorthodox approach being proposed by EPFL researchers, patients may soon be able to track their illness simply by drinking a solution containing millions of tiny electronic sensors disguised as bacteria. Imagine being able to track the development of diseased cells in real time, simply by having patients drink a glass of water containing millions of tiny electronic biosensors.

Smart buildings that can manage our electricity needs
Researchers at EPFL have developed a system that can be installed in a building to collect data on people's energy usage. The aim is then to send this data directly to a smart electric grid that will allocate resources optimally. A smart grid that decides how best to distribute energy based on availability, cost and customers' needs - that's the energy concept being developed by researchers in the School of Engineering's Electronics Laboratory.

A 100-year-old physics problem has been solved at EPFL
EPFL researchers have found a way around what was considered a fundamental limitation of physics for over 100 years. They were able to conceive resonant systems that can store electromagnetic waves over a long period of time while maintaining a broad bandwidth. At EPFL, researchers challenge a fundamental law and discover that more electromagnetic energy can be stored in wave-guiding systems than previously thought.
