As microplastics and their smaller, even more insidious counterparts, nanoplastics, have increasingly permeated the environment and our bodies, one of the key challenges facing researchers has been ...

Researchers at the University of Gothenburg have made light-powered gears on a micrometer scale. This paves the way for the smallest on-chip motors in history, which can fit inside a strand of hair.

Each gear is about 0.016 mm in diameter. Credit: Gan Wang Researchers at the University of Gothenburg have made light-powered gears on a micrometer scale. This paves the way for the smallest on-chip ...

Researchers from Massachusetts Institute of Technology (MIT) and University of Chemistry and Technology Prague created a ...

A self-powered fabric with nanostructured materials converts sound into electrical signals and uses deep learning to ...

For the smallest motors, nothing gets the gears turning like laser beams. After years of trying to make gears more compact, scientists have now created ones on a micrometer scale that run entirely on ...

Researchers at the University of Gothenburg have announced an interesting invention: the “smallest on-chip motor in history.” Surprisingly, this tiny motor is so small that it can fit “inside a strand ...

A team of researchers in China has developed a lens-free imaging system that produces sharp mid-infrared images even in low light and across long distances. The breakthrough promises improvements for ...

Abstract: In this paper, we propose a low-profile, transmissive, linearly polarized, 4-bit metasurface operating at 195 GHz. The meta-atom of the metasurface consists of three metal layers: a resonant ...

Abstract: The small wavelength, typically in the range of millimeters to micrometers, makes characterisation of antennas at sub-THz band particularly challenging as it requires measurement systems to ...
