The research team explored how millimeter-wave radar sensors could be used to remotely track a person’s heart rate without ...
Imagine sitting at your desk during a normal workday. You log into your computer, unaware that a built-in sensing system ...
A countermeasure called MetaHeart can mislead 'heartrate radar' by reflecting back a fabricated pattern as a kind of biometric decoy.
It's a typical workday and you sign onto your computer. Unbeknownst to you, a high-frequency sensing system embedded in your ...

The work, reported in Optica by scientists from Tianjin University and Nanyang Technological University, marks the first experimental realization of skyrmions that can be actively toggled ...
Scientists have generated ultra-stable, donut-shaped light structures called skyrmions. These innovative beams can carry data ...
A new optical device allows researchers to generate and switch between two stable, donut-shaped light patterns called ...
Researchers have created an optical device that can generate both electric and magnetic vortex-ring-like light patterns. These structured light vortices, known as skyrmions, are highly stable and ...
Researchers use large language models to streamline nanoscopic material design for advanced optical systems like camera lenses and VR headsets. (Nanowerk News) A team of researchers at Penn State have ...
