Microscopic Machines Powered by Light Achieve Milestone
- Scientists developed microscopic machines with functional gears, racks, and pinions driven solely by photon momentum.
- The devices are created using standard semiconductor fabrication tools and could potentially power microfluidic pumps and reconfigurable optics.
- Current efficiency is extremely low, with only one ten-trillionth of the light’s energy converted into motion.
These microscopic machines represent a significant breakthrough in integrating photonics with mechanics at micrometer scales, offering potential applications in fields like biomedical research and data centers. However, they currently serve as a proof-of-concept due to their low efficiency and operational challenges.
The achievement showcases the possibility of powering mechanical motion with light, but further developments are needed to improve efficiency and practical usability. Source
