3. Mechanical Impedance

   French, Mark (April 2019, American lutherie)

   We all know what “impedance” is, right? It’s that stuff... the force that... well, what is it really? Turns out it’s something like pushing a kid on a swing at the wrong time. And it has a lot to do with the resonances of acoustic instruments, which has a lot to do with how they sound. Anyway, Professor Mark gives us the scoop.

5. Toward mechanical proprioception in autonomously reconfigurable kirigami-inspired mechanical systems

   https://doi.org/10.1098/rsta.2024.0116

   Mechanical metamaterials have recently been exploited as an interesting platform for information storing, retrieval and processing, analogous to electronic devices. In this work, we describe the design and fabrication a two-dimensional (2D) multistable metamaterial consisting of building blocks that can be switched between two distinct stable phases, and which are capable of storing binary information analogous to digital bits. By changing the spatial distribution of the phases, we can achieve a variety of different configurations and tunable mechanical properties (both static and dynamic). Moreover, we demonstrate the ability to determine the phase distribution via simple probing of the dynamic properties, to which we refer as mechanical proprioception. Finally, as a simple demonstration of feasibility, we illustrate a strategy for building autonomous kirigami systems that can receive inputs from their environment. This work could bring new insights for the design of mechanical metamaterials with information processing and computing functionalities. This article is part of the theme issue ‘Origami/Kirigami-inspired structures: from fundamentals to applications’.
