Soft and disordered hyperuniform elastic metamaterials for highly efficient vibration concentration
文献摘要：
Vibrations,which widely exist throughout the world,could be a nearly endless and locally obtained green energy source.It has been a long-standing challenge to efficiently utilize dispersed vibration energy,especially within the high-frequency range,since the amplitudes of high-frequency vibrations in local parts of objects are relatively weak.Here,for the first time,we propose a soft and disordered hyperuniform elastic metamaterial (DHEM),achieving a remarkable concentration of vibrations in broad frequency bands by a maximum enhancement factor of～4000 at 1930 Hz.The DHEM,with rational sizes from ～ 1 cm to～ 1000 cm,covers a broad range of frequencies from ～ 10 Hz to ～ 10 kHz,which are emitted by many vibration sources including domestic appliances,factories and transportation systems,for example.Moreover,the performance of the soft DHEM under deformation is validated,enabling conformal attachments on uneven objects.Our findings lay the groundwork for reducing traditional energy consumption by recovering some of the energy dissipated by devices in the working world.
