An actuator and/or sensor elastic component with a three-fold periodic membrane or rod structure

摘要

An elastic component (1) has a main structure (2) which fills a volume (3) between a first surface (4) and a second surface (5). The first surface (4) extends along a surface whose Cartesian coordinates x, y, and z satisfy one of the following three equations, in which L is a lattice constant: $-\text{cos}\left(\frac{2\mathrm{\pi }}{L}x\right)+\text{cos}\left(\frac{2\mathrm{\pi }}{L}y\right)+\text{cos}\left(\frac{2\mathrm{\pi }}{L}z\right)=0$$-\text{sin}\left(\frac{2\mathrm{\pi }}{L}x\right)\text{cos}\left(\frac{2\mathrm{\pi }}{L}y\right)+\text{sin}\left(\frac{2\mathrm{\pi }}{L}y\right)\text{cos}\left(\frac{2\mathrm{\pi }}{L}z\right)+\text{cos}\left(\frac{2\mathrm{\pi }}{L}x\right)\text{sin}\left(\frac{2\mathrm{\pi }}{L}z\right)=0$ or $\begin{array}{c}-sin\left(\frac{2\mathrm{\pi }}{L}x\right)sin\left(\frac{2\mathrm{\pi }}{L}y\right)sin\left(\frac{2\mathrm{\pi }}{L}z\right)+sin\left(\frac{2\mathrm{\pi }}{L}x\right)cOs\left(\frac{2\mathrm{\pi }}{L}y\right)cOs\left(\frac{2\mathrm{\pi }}{L}z\right)+\\ cOs\left(\frac{2\mathrm{\pi }}{L}x\right)sin\left(\frac{2\mathrm{\pi }}{L}y\right)cOs\left(\frac{2\mathrm{\pi }}{L}z\right)+cOs\left(\frac{2\mathrm{\pi }}{L}x\right)cOs\left(\frac{2\mathrm{\pi }}{L}y\right)sin\left(\frac{2\mathrm{\pi }}{L}z\right)=\mathrm{0th}\end{array}$ The main structure (3) has a functional material (6), which can be controlled by a physical control signal to a change in shape and / or responds to a change in shape with a physical response signal; and on the first surface (4) and the second surface (5), line assemblies (7, 8) are arranged to cause the drive signal and / or to interrogate the response signal.
