Researchers develop contact lenses to diagnose glaucoma
A team from the UK and Turkey have developed a contact lens with embedded micro-sensors which can detect changes in eye pressure - a possible indicator of glaucoma.

Spinal fusion—fusing two vertebrae together—can treat a wide variety of spinal disorders. A patient-specific 3D-printed smart metamaterial implant doubles as sensor to monitor spinal healing.
Anyone needing a tomography gets the clearest possible images of an organ or other body structure slice by slice. But the further inside the potential problem lies, the more difficult it is to obtain high-resolution images in magnetic resonance imaging (MRI). An international team of scientists led by the University of Duisburg-Essen (UDE) has developed a high-frequency coil that allows for much…
MRI is a complicated imaging modality and improving it requires a deep understanding of the physics involved. Scientists at Boston University have been working on improving MRI’s signal-to-noise ratio using special metamaterials that are made of arrays of helical resonators.
A group of researchers from Russia, Australia and the Netherlands have developed a technology that can reduce Magnetic Resonance Imaging (MRI) scanning times by more than 50 percent, meaning hospitals can drastically increase the number of scans without changing equipment. This extraordinary leap in efficiency is achieved by placing a layer of metamaterials onto the bed of the scanner, which…
