“…The X-ray magnetic circular dichroism and temperature dependence of magnetization show that VH is ferrimagnetic with a high T c of 360 K (Supplementary Fig. 7b ), while IM is ferroelectric with T c of 373 K 23 , 33 . Complex geometric heterostructures (Schwarz primitive structure, lattice structure, and minimal surface structures) could be rapidly printed (Fig.…”

The convergence of proton conduction and multiferroics is generating a compelling opportunity to achieve strong magnetoelectric coupling and magneto-ionics, offering a versatile platform to realize molecular magnetoelectrics. Here we describe machine learning coupled with additive manufacturing to accelerate the design strategy for hydrogen-bonded multiferroic macromolecules accompanied by strong proton dependence of magnetic properties. The proton switching magnetoelectricity occurs in three-dimensional molecular heterogeneous solids. It consists of a molecular magnet network as proton reservoir to modulate ferroelectric polarization, while molecular ferroelectrics charging proton transfer to reversibly manipulate magnetism. The magnetoelectric coupling induces a reversible 29% magnetization control at ferroelectric phase transition with a broad thermal hysteresis width of 160 K (192 K to 352 K), while a room-temperature reversible magnetic modulation is realized at a low electric field stimulus of 1 kV cm−1. The findings of electrostatic proton transfer provide a pathway of proton mediated magnetization control in hierarchical molecular multiferroics.

“…Recently, 3D‐printed piezo‐electric materials crossed this barrier and have been developed to convert mechanical movement, impact, and stress from any direction into electrical energy. [ 182–187 ] This could be highly attractive considering the high abundance of organic and organic‐inorganic hybrid piezoelectric materials that are known today. The next step would be fabricating 3D‐printed low‐cost organic and organic–inorganic hybrid piezoelectric materials for flexible smart sensor devices for high‐technology applications. There is a need to provide performance data in a systematic fashion.…”

This article provides a comprehensive overview of piezo-and ferro-electric materials based on organic molecules and organic-inorganic hybrids for mechanical energy harvesting. Molecular (organic and organic-inorganic hybrid) piezo-and ferroelectric materials exhibit significant advantages over traditional materials due to their simple solution-phase synthesis, light-weight nature, thermal stability, mechanical flexibility, high Curie temperature, and attractive piezo-and ferroelectric properties. However, the design and understanding of piezo-and ferroelectricity in organic and organic-inorganic hybrid materials for piezoelectric energy harvesting applications is less well developed. This review describes the fundamental characterization of piezo-and ferroelectricity for a range of recently reported organic and organic-inorganic hybrid materials. The limits of traditional piezoelectric harvesting materials are outlined, followed by an overview of the piezo-and ferroelectric properties of organic and organic-inorganic hybrid materials, and their composites, for mechanical energy harvesting. An extensive description of peptide-based and other biomolecular piezo-and ferroelectric materials as a biofriendly alternative to current materials is also provided. Finally, current limitations and future perspectives in this emerging area of research are highlighted. This perspective aims to guide chemists, materials scientists, and engineers in the design of practically useful organic and organic-inorganic hybrid piezo-and ferroelectric materials and composites for mechanical energy harvesting.

“…Multi-material micro-SLA has also recently been demonstrated, with several coloured resins used in a single print and a layer thickness of 30 μm [111], illustrated in Figure 16 for the multi-colour print at 200 μm scale. An active AMM has also been fabricated with ferroelectric material, allowing tuneable stiffness via an external electric field [112]. The efficiency of this method is limited due to the scanning mechanism, which is required to move across the vat incrementally to cure a layer.…”

Additive Manufacture of Small-Scale Metamaterial Structures for Acoustic and Ultrasonic Applications

Acoustic metamaterials are large-scale materials with small-scale structures. These structures allow for unusual interaction with propagating sound and endow the large-scale material with exceptional acoustic properties not found in normal materials. However, their multi-scale nature means that the manufacture of these materials is not trivial, often requiring micron-scale resolution over centimetre length scales. In this review, we bring together a variety of acoustic metamaterial designs and separately discuss ways to create them using the latest trends in additive manufacturing. We highlight the advantages and disadvantages of different techniques that act as barriers towards the development of realisable acoustic metamaterials for practical audio and ultrasonic applications and speculate on potential future developments.
