KEZAKO: Comment l'oeil voit-il? Simulation flash Lentille sphérique mince. Nous allons tous devenir myopes : voici pourquoi. Ultrathin lens could revolutionise next-gen devices. Researchers at Swinburne University of Technology, collaborating with Monash University, have developed an ultrathin, flat, ultra-lightweight graphene oxide optical lens with unprecedented flexibility.

The ultrathin lens enables potential applications in on-chip nanophotonics and improves the conversion process of solar cells. It also opens up new avenues in: non-invasive 3D biomedical imagingphotonic chipsaerospace photonicsmicromachineslaser tweezing – the process of using lasers to trap tiny particles.

Quelques expériences pour mettre en évidence les propriétés de l'oeil. Engineers develop 'smart glasses' that automatically focus on what wearer sees. The days of wearing bifocals or constantly swapping out reading glasses might soon come to an end.

Engineers develop 'smart glasses' that automatically focus on what wearer sees

A team led by University of Utah electrical and computer engineering professor Carlos Mastrangelo and doctoral student Nazmul Hasan has created "smart glasses" with liquid-based lenses that can automatically adjust the focus on what a person is seeing, whether it is far away or close up. Research on the adaptive lenses was published this week in a special edition of the journal, Optics Express. The paper was co-authored by U electrical and computer engineering associate professor Hanseup Kim and graduate researcher Aishwaryadev Banerjee.

"Most people who get reading glasses have to put them on and take them off all the time," says Mastrangelo, who also is a professor for USTAR, the Utah Science Technology and Research economic development initiative. "You don't have to do that anymore.
