Накратко на български

Меки магнитоактивни метаматериали позволяват дистанционно управление на еластични вълни, например чрез потискане на нискочестотни вибрации. Това помага за подобряване на шумоизолацията и защитата в авиацията, автомобилостроенето и медицината.

Soft magnetoactive metamaterials for remote tunability of elastic waves

The MetaMagic project was initiated to address critical limitations in current wave control and mechanical signal processing technologies, particularly in sectors requiring real-time adaptability, vibration isolation, energy harvesting, and stealth capabilities. Conventional mechanical and acoustic metamaterials are typically passive, with limited tunability and ability to respond dynamically to changing environments. To overcome these challenges, the project focused on developing a new class of materials known as Soft Magnetoactive Metamaterials (SMMs). These materials are programmable, reconfigurable, and multifunctional, capable of actively and remotely manipulating elastic waves. By exploiting magneto-mechanical coupling in soft elastomers embedded with magnetic particles, SMMs offer unprecedented control over complex wave phenomena—including broadband low-frequency attenuation, topologically protected edge state, invisible cloaking, and nonlinear solitary wave propagation. The overarching objective of MetaMagic was to establish the theoretical foundations, computational modeling tools, and experimental validation necessary to realize these innovative materials. In doing so, the project positions SMMs as transformative solutions for real-world applications across aerospace, automotive, biomedical, and civil infrastructure sectors. MetaMagic has laid a robust scientific foundation with the potential to significantly advance the fields of smart materials, mechanical metamaterials, and programmable matter.

Цел на проекта

Due to striking advantages such as rapid response and reversible change in the shape and properties under remotely applied magnetic fields, soft magnetoactive materials have become an attractive material platform for human-technology interfaces, soft robotics, actuators and sensors, and biomedical devices. However, a systematic understanding of their dynamic behaviors in the extreme regime is still lacking, creating a bottleneck to innovation and limiting their tremendous potential in nondestructive testing, energy harvesting, and smart soft wave devices.MetaMagic aims at developing an experimentally-informed framework to design and discover novel Soft Magnetoactive Metamaterial systems with tunable and unusual elastic wave characteristics beyond the wavelength limit, with a view to industrial applications in the design of smart wave manipulation devices. The project proposes to exploit the Unique Transformative Ability of soft magnetoactive materials integrated into the Neat Metamaterial Design incorporating the local resonance and topological phase transition, polar and asymmetric, and nonlinear vector solitary effects.The action mixes ad-hoc theoretical modelling with experimental tests and numerical simulations, by fully leveraging the host and secondment institutions' expertise and facilities, and experience in scientific management. The training programme is structured to strengthen my interdisciplinary skills and will allow me to grow as a world-class leader in the emerging field of tunable and reconfigurable metamaterials.The output of this action will open new levels of performance in a variety of advanced applications, from broadband vibration isolation at challenging low-frequency ranges to robust energy harvesting with ultra-high transmission rates. Ultimately, MetaMagic will advance the frontier of knowledge about reconfigurable soft metamaterials – contributing to Horizon Europe's policy and strategy in the key area of ""Advanced Materials"".""
