This paper proposes a three-dimensional lever-type inertial amplification metamaterial for the mitigation of low-frequency vibration. This metamaterial was developed as a small. stiff. and single-phase structure that can inhibit the transmission of vibration in a certain frequency range below 100 Hz. https://www.bekindtopets.com/super-value-Crushed-Turquoise-iPhone-14-Pro-Max-MagSafe-Case-p82210-mega-value/
