Today at the ISASI Workshop, Dr. Domenico Sagnelli (Institute of Applied Sciences and Intelligent Systems “E. Caianiello”, CNR – Pozzuoli, Italy) presented his recent research on nanoparticles and photomobile polymers as a breakthrough in the development of light-driven actuators.
The talk highlighted results from two major projects:
- PULSE-COM Project (2019–2023): Focused on developing photo-piezo-actuators based on light-sensitive composites.
- ALICE Project (2022–2024): Aiming to create a new class of actuator platforms to convert light into mechanical energy for applications such as soft robotics and solar energy harvesting.
Key innovations discussed included:
- The use of azobenzene-based photo-switchable molecules to store and release energy via light-induced isomerization.
- Doping photomobile polymers with ZnO nanoparticles, which enhances bending ability when stimulated with light.
- Advances in 4D printing technologies, enabled by ZnO doping, that eliminate the need for mechanical rubbing and expand possibilities for smart materials.
- Several international patent applications, marking significant steps toward real-world applications in solar tracking, energy generation, and advanced actuator systems.
Dr. Sagnelli’s work demonstrates how light-responsive smart materials can pave the way for innovative energy solutions and next-generation devices.
