“…Our modeling may direct nanocomposite development towards this area of highly‐flexible and high‐response nanocomposites (see Section S7 and Figure S5 in the Supporting Information). We compared the designed performance of the piezoelectric nanocomposite with that of existing 3D printed piezoelectrics6a,11,12,29. As shown in Figure , the designed nanocomposite exceeds the functional property of other 3D printable piezoelectrics, while occupying a wide range of compliance range (i.e., from 5.5 × 10 −11 to 3 × 10 −8 Pa −1 ).…”

“…Additionally, the incompatibilities between high stiffness nanoparticle and low stiffness polymer, resulting in poor interfacial adhesion, reduce stress transfer efficiency from the polymer matrix to the piezoelectric inclusions, and suppress the functional performance. Increasing the matrix stiffness was previously shown to be key to enhancing piezoelectric response, but it remains unclear if highly‐responsive flexible piezoelectric materials are possible.…”

“…Recent studies have explored surface functionalization of a low concentration of BTO nanoparticles (below 2 vol%, i.e., 10 wt%) to covalently bind them to the polymer matrix, and have demonstrated appreciable enhancement of the piezoelectric coefficient as compared to nonfunctionalized dispersion . This surface functionalization can enhance particle–polymer compatibility, and enables the production of complex, 3D piezoelectric microarchitectures with high concentrations of piezoelectric nanoparticles while maintaining processability 1b.…”

The trade-off between processability and functional responses presents significant challenges for incorporating piezoelectric materials as potential 3D printable feedstock. Structural compliance and electromechanical coupling sensitivity have been tightly coupled: high piezoelectric responsiveness comes at the cost of low compliance. Here, the formulation and design strategy are presented for a class of a 3D printable, wearable piezoelectric nanocomposite that approaches the upper bound of piezoelectric charge constants while maintaining high compliance. An effective electromechanical interphase model is introduced to elucidate the effects of interfacial functionalization between the highly concentrated perovskite nanoparticulate inclusions (exceeding 74 wt%) and light-sensitive monomer matrix, shedding light on the significant enhancement of piezoelectric coefficients. It is shown that, through theoretical calculation and experimental validations, maximizing the functionalization level approaches the theoretical upper bound of the piezoelectric constant d 33 at any given loading concentration. Based on these findings, their applicability is demonstrated by designing and 3D printing piezoelectric materials that simultaneously achieve high electromechanical sensitivity and structural functionality, as highly sensitive wearables that detect low pressure air (<50 Pa) coming from different directions, as well as wireless, self-sensing sporting gloves for simultaneous impact absorption and punching force mapping.barium titanate (BTO) [5] are the most frequently used piezoelectric ceramic materials for transducer applications. Direct 3D printing of piezoelectric-polymer composites offers a promising solution to fabricating complex piezoelectrics beyond conventional ceramic processing methods which require extensive, time-consuming sintering, may have residual porosity, and have brittle responses. However, due to the functionality-processability tradeoff, the resulting piezoelectric response of the printed nanocomposite is over two ordersof-magnitude lower than pure ceramic. [6] Increasing particle concentration leads to agglomeration, [7] high viscosity, [8] and significant light absorption, [9] making it difficult to manufacture fully complex microarchitectures or free form-factors. Additionally, the incompatibilities between high stiffness nanoparticle and low stiffness polymer, resulting in poor interfacial adhesion, [10] reduce stress transfer efficiency from the polymer matrix to the piezoelectric inclusions, and suppress the functional performance. Increasing the matrix stiffness was previously shown to be key to enhancing piezoelectric response, [11] but it remains unclear if highly-responsive flexible piezoelectric materials are possible.Recent studies have explored surface functionalization of a low concentration of BTO nanoparticles (below 2 vol%, i.e., 10 wt%) to covalently bind them to the polymer matrix, and have demonstrated appreciable enhancement of the piezoelectric coefficient 3D Printed Nanocomposi...

“…Ink-modified BaTiO 3 nanoparticles were incorporated into poly(ethylene glycol diacrylate) (PEGDA) composite film devices, and a d 33 value of approximately 80 pC/N was found. [115] A BaTiO 3 /PDMS composite film with a 20 wt% mass ratio of BaTiO 3 nanoparticles exhibited the highest performance (output voltage of approximately 14 V). [116] The effects of the contents of multi-walled carbon nanotubes (MWCNT) (0.0-5.0 wt%) and BaTiO 3 nanofibers (10-50 wt%) on the electrical, dielectric, and piezoelectric properties of PDMS-based nanogenerators were systematically investigated.…”

In the coming era of the internet of things (IoT), wireless sensor networks that monitor, detect, and gather data will play a crucial role in advancements in public safety, human healthcare, industrial automation, and energy management. Batteries are currently the power source of choice for operating wireless network devices due to their ease of installation; however, they require periodic replacement due to capacity limitations. Within the scope of the IoT, battery maintenance of the trillion sensor nodes that may be implemented will be practically infeasible from environmental, resource, and labor cost perspectives. In considering individual self-powered sensor nodes, the idea of harvesting energy from ambient vibrations, heat, and electromagnetic waves has recently triggered noticeable research interest in the academic community. This paper gives an overview of energy harvesting materials and systems. Three main categories are presented: piezoelectric ceramics/polymers, magnetostrictive alloys, and magnetoelectric (ME) multiferroic composites. State-of-the-art harvesting materials and structures are presented with a focus on characterization, fabrication, modeling and simulation, and durability and reliability. Some perspectives and challenges for the future development of energy harvesting materials are also highlighted.

“…The crosslinking of the polymer with the chemical groups on the piezoelectric nanoparticles enhanced the piezoelectric output of the composite films by channeling mechanical stress to the piezoelectric crystals. The authors have also recently shown that fine‐tuning the size of the nanoparticles and linker molecules can increase stress transfer between the composite matrix and the surface of the nanoparticles 368. For example, when a polymer with higher molecular weight is used, the increased molecular interactions between the nanoparticles and polymer increases stress transfer through the material by increasing the number of functionalized deformation modes.…”

The synergistic integration of nanomaterials with 3D printing technologies can enable the creation of architecture and devices with an unprecedented level of functional integration. In particular, a multiscale 3D printing approach can seamlessly interweave nanomaterials with diverse classes of materials to impart, program, or modulate a wide range of functional properties in an otherwise passive 3D printed object. However, achieving such multiscale integration is challenging as it requires the ability to pattern, organize, or assemble nanomaterials in a 3D printing process. This review highlights the latest advances in the integration of nanomaterials with 3D printing, achieved by leveraging mechanical, electrical, magnetic, optical, or thermal phenomena. Ultimately, it is envisioned that such approaches can enable the creation of multifunctional constructs and devices that cannot be fabricated with conventional manufacturing approaches.
