Light-Driven Mechanical Systems
The ability of light to exert forces on objects has profound implications across physics and engineering. This phenomenon, known as radiation pressure, where photons impart momentum to matter, can be observed for example, in the gentle push of solar radiation on the dust tail of comets, resulting in the distinctive tail pointing away from the sun.
In recent years, the concept of light-driven propulsion has gained traction, opening new avenues for remote object manipulation and propulsion. One notable example is in space exploration, where solar sails use the pressure of sunlight to propel a spacecraft, or the recent idea of light sails that are propelled by intense laser beams. By reflecting photons, these sails achieve a small but continuous thrust, allowing them to reach remarkable speeds over time without the need for conventional fuel.
Our research aims to explore innovative methods and materials for enhancing light-driven propulsion systems and the micro- and macroscale. By investigating advanced materials that can respond optimally to light, we hope to develop more efficient and powerful propulsion mechanisms. Such advancements could transform the future of micro-robotics, space exploration, and sensing in remote areas.
