Scientists made a material that can 'catch' a shockwave and hold onto its energy so you can use it later.

Why it matters
Normally, when you hit an object, the energy vibrates through it and vanishes as heat. This new 'metamaterial' uses special topological waves to cage the impact energy at a designed location, allowing it to act as both a perfect shock absorber and a battery.
From the abstract
The presence of multiple stable states and associated nonlinear phenomena, such as hysteresis, in multistable mechanical metamaterials enables frequency-independent energy harvesting and shock absorption. This study focuses on shock absorption achieved by locking transition waves to trap energy at designed locations within a multistable metamaterial. We further demonstrate that the same system can simultaneously harvest energy from impact loading, thereby exhibiting multifunctionality. The model
