LED fitted soft eye contact lense
The graphene-mNW hybrid structure developed by the UNIST research team is a new class of electrodes and may soon find use in a variety of other applications. The research team demonstrated Inorganic light-emitting diode (ILED) devices fitted on a soft eye contact lens using the transparent, stretchable interconnects of the hybrid electrodes as an application example.
As an in vivo study, this contact lens was worn by a live rabbit eye for five hours and no abnormal behavior, such as bloodshot eye or the rubbing of eye areas were observed in the live rabbit. Wearing eye contact lenses, picture-taking and scanning, is not science fiction anymore.
The research was led by Jang-Ung Park, professor of the School of Nano-Bioscience and Chemical Engineering at UNIST. “We believe the hybridization between two-dimensional and one-dimensional nanomaterials presents a promising strategy toward flexible, wearable electronics and implantable biosensor devices, and indicate the substantial promise of future electronics,” said Prof. Park.

New Project SNAPSTER: Novel luminescent materials by encapsulating phosphorescent metal clusters with organic liquid crystals
Nowadays energy conversion in lighting and optoelectronic devices requires the use of rare earth oxides.
Scientists have discovered the first synthetic material that becomes thicker - at the molecular level - as it is stretched.
Researchers led by Dr Devesh Mistry from the University of Leeds discovered a new non-porous material that has unique and inherent "auxetic" stretching...
