Bifocal Lenses, with Liquid Crystal Bilayers, Allow Flexible Light Modulation
A bilayer, bifocal lens with adjustable focal points could allow more flexible modulation of light in applications for optical computing, bioimaging, AR and VR, and other areas. The lens, which was developed at Hunan University, is composed of bilayer structures made with a liquid crystal cell and liquid crystal polymer. Each liquid crystal layer has a different function in controlling light modulation.

Spectroscopic Headset Could Reveal Stroke Risk
Clinicians have historically been at a disadvantage in successfully identifying those at grave risk of having a stroke ahead of time. A team from the California Institute of Technology and Keck School of Medicine of the University of Southern California has created a headset based on relatively basic laser and detector technology that could be fitted on patients to dramatically change the health trajectory of those at risk.

OLED Tech Provides Optogenetic Light Source for Cochlear Implants
To advance the development of optical cochlear implants (oCIs), the Fraunhofer Institute for Photonic Microsystems (Fraunhofer IPMS) is collaborating with the Max Planck Institute for Multidisciplinary Natural Sciences and University Medical Center Göttingen to evaluate its OLED-on-silicon technology for use in optical cochlear implants. The IPMS team, which originally developed the technology for microdisplays, has created miniature OLED-on-silicon probes to use as optical stimulators in oCIs.
