Light That Adapts to Your Needs Through the Eye of a Camera
Light That Adapts to Your Needs Through the Eye of a Camera
Researchers have developed a camera that sees like the human eye, providing clues about the sensation of visual comfort. The instrument could optimize natural and artificial lighting to constantly adapt to the needs of the user. How can we combine visual comfort with electrical energy savings? Light inside the home is a theme that has interested researchers for over a half century.

Heat Waves in Graphene
Heat Waves in Graphene
EPFL researchers have shed new light on the fundamental mechanisms of heat dissipation in graphene and other two-dimensional materials. They have shown that heat can propagate as a wave over very long distances. This is key information for engineering the electronics of tomorrow. In the race to miniaturize electronic components, researchers are challenged with a major problem: the smaller or the faster your device, the more challenging it is to cool it down.

Spannungsprüfer für schlagende Herzzellen
Spannungsprüfer für schlagende Herzzellen
Wissenschaftlern gelang es erstmals, den Strom durch Membrankanäle in schlagenden Herzmuskelzellen zu messen. Dazu kombinierten sie ein Rasterkraftmikroskop mit einem breit eingesetzten Verfahren zur Messung von elektrischen Signalen in Körperzellen. Elektrische Impulse spielen in Körperzellen eine wichtige Rolle.

Electronic circuits with reconfigurable pathways closer to reality
Electronic circuits with reconfigurable pathways closer to reality
Multitasking circuits capable of reconfiguring themselves in real time and switching functions as the need arises - this is the promising application stemming from a discovery made at EPFL and published. Other potential uses: miniaturising our electronic devices and developing resilient circuits. Will it be possible one day to reconfigure electronic microchips however we want, even when they are in use? A recent discovery by a team at EPFL suggests as much.

Graphene multiplies the power of light
Graphene multiplies the power of light
Could graphene turn light to electricity? Scientists have shown that graphene can convert a single photon into multiple electrons, showing much promise for future photovoltaic devices. Graphene is a material that has gathered tremendous popularity in recent years, due to its extraordinary strength and light weight.

Useful for spintronics: Big surprises in a thin surface region
Useful for spintronics: Big surprises in a thin surface region
The need for ever faster and more efficient electronic devices is growing rapidly, and thus the demand for new materials with new properties. Oxides, especially ones based on strontium titanate (SrTiO 3 ), play an important role here. Researchers recently discovered that SrTiO 3 , although actually an insulator, can form a metallic layer on its surface, in which electric current can flow.
