TLDR
In this article, a lattice structure based on bimorph rib elements is fabricated and studied experimentally, and the effective piezoelectric sensitivity d is observed to be much larger, by a factor of at least 10 000, in magnitude than that of material comprising the lattice ribs.Abstract:
Lattice structures based on bimorph rib elements are fabricated and studied experimentally. The effective piezoelectric sensitivity d is observed to be much larger, by a factor of at least 10 000, in magnitude than that of material comprising the lattice ribs. Bending of the ribs in response to input voltage is responsible for the large sensitivity.read more

Chiral three-dimensional lattices with tunable Poisson’s ratio
TL;DR: In this paper, a chiral three-dimensional cubic lattice with rigid cubical nodules was developed with finite element analysis and the lattices exhibit geometry dependent Poisson's ratio that can be tuned to negative values.

Controllable thermal expansion of large magnitude in chiral negative Poisson's ratio lattices
TL;DR: In this paper, a planar chiral lattice structure with Poisson's ratio approaching -1 is presented for controlled thermal expansion, which can be arbitrarily large positive or negative.

Tailoring Poisson's ratio by introducing auxetic layers
TL;DR: In this paper, Monte Carlo simulations in the isobaric-isothermal ensemble with variable shape of the periodic box are used to study elastic properties of two-dimensional (2D) model systems of hard discs with parallel layers of hard cyclic hexamers.

TL;DR: In this article , the authors report a design and manufacturing route to create a class of robotic metamaterials capable of motion with multiple degrees of freedom, amplification of strain in a prescribed direction in response to an electric field (and vice versa), and thus, programmed motions with self-sensing and feedback control.

The Theory of Composites
TL;DR: Some of the greatest scientists including Poisson, Faraday, Maxwell, Rayleigh, and Einstein have contributed to the theory of composite materials Mathematically, it is the study of partial differential equations with rapid oscillations in their coefficients Although extensively studied for more than a hundred years, an explosion of ideas in the last five decades has dramatically increased our understanding of the relationship between the properties of the constituent materials, the underlying microstructure of a composite, and the overall effective moduli which govern the macroscopic behavior as mentioned in this paper.

Connectivity and piezoelectric-pyroelectric composites
TL;DR: In this article, a series and parallel model for composite piezoelectric and pyroelectrics is presented, which leads to several interesting results, such as a diphasic pyroelectric in which neither phase is pyrocharged.

Damping of structural vibrations with piezoelectric materials and passive electrical networks
TL;DR: In this paper, the authors investigated the possibility of dissipating mechanical energy with piezoelectric material shunted with passive electrical circuits, and derived the effective mechanical impedance for the piezolectric element shunted by an arbitrary circuit.
