In a groundbreaking development, scientists at Friedrich-Alexander-Universität Erlangen-Nürnberg (FAU) have unveiled materials that can change shape and mechanical properties when exposed to light. This pioneering research, led by Professor Dr. Henry Dube, introduces a new era of intelligent materials that could revolutionize fields ranging from robotics to healthcare.
The research focuses on molecular machines, tiny mechanical components made up of just a few dozen atoms. By scaling these into intricate three-dimensional structures, the team aims to create materials capable of performing complex physical tasks in response to light stimuli.
Professor Dube’s initiative goes beyond traditional electronics, using atomic-scale components to achieve large-scale effects. Previously, Dr. Dube has crafted individual nanomotors, gears, and tweezers. Now, the goal is to link these into polymers that exhibit coordinated motion, akin to biological systems like human muscles.
The project employs light pulses as the key control mechanism. Exposure to certain light wavelengths causes the nanomachines to reshape and even change color, enabling remote control without wiring. This feature has potential applications in creating dynamic 3D displays and programmable materials that alter their rigidity based on light color.
Supported by a grant of approximately 900,000 euros from the Volkswagen Foundation, the project aims to refine these materials over the next four years. Dr. Dube envisions a future where these innovations lead to more sustainable and versatile solutions across various industries.
