Abstract: This paper presents a highly sensitive microwave groove gap waveguide displacement sensor based on the interferometry technique. By using the interferometric measurement, environmental ...

Deep cleaning your microwave often falls low on the list of household cleaning priorities—unless, of course, you’ve just faced a tomato soup explosion or a butter-softening mishap. It’s one ...

Starting in the fourth quarter of 2025, the republic’s Land Transport Authority (LTA) will replace its 11,500 mechanical pedestrian push buttons with touchless microwave sensors. It works by detecting ...

The microwave sensors detect hand movements by emitting electromagnetic waves and relying on changes in the frequency of the waves reflected into the device. The infrared sensors rely on changes ...

The new touchless buttons will be operated through the use of microwave sensors where pedestrians can simply wave their hands in front of the button to activate it. The new touchless sensors ...

Beginning from the fourth quarter of 2025, the Land Transport Authority (LTA) will replace all existing mechanical pedestrian push buttons with touchless microwave sensors that detect hand ...

One of the most exciting developments is the supposed introduction of a new 1-inch 200MP ISOCELL image sensor for the Galaxy S25 Ultra's main camera. This larger sensor size promises to deliver ...

In this article, we develop a novel spatial displacement measurement approach with a single microwave transceiver, creating the first unique 3-D microwave displacement sensor (3D-MDS), which can get ...
