Hybrid Three-Dimensional Deposition and Development (H3D) of Multiferroic Electroceramics for Advanced Nanomaterials-Defined Sensors and Actuators (H3D-MEandSA)
Abstract
Breaking from the traditional cost- and labor-intensive approach in making electroceramiccomposite devices, this project explores a new paradigm for direct fabrication of multicomponent compact electroceramic sensors and actuators in a hybrid additive process. De spite 3D printings ubiquity in plastic prototyping, 3D printing of electroceramics or functional composites are still in its infanc y.The objective is to establish a research platform on hybrid 3D design and fabrication ofMultiferroic Electroceramics for Advance d Nanomaterials-Defined Sensors and Actuators (H3DMEandSA). The advanced sensors and actuators will be composed of multiferroic(fer roelectrics/piezoelectrics and/or ferromagnetics/magnetostrictives), dielectric, semiconducting, and conducting constituents, with d esired 3D patterns/connectivity, of nm (transversal) to micrometer (lateral) controlled resolution, and with tailored performance de termined by the figureof-merit of the given sensor or actuator applications. This project will develop a family of electroceramic so lid colloids (inks) or aerosols in which high performance piezoelectric or magnetostrictive nanoparticles are dispersed or encapsula ted. The materials development and digital H3D fabrication will be accompanied by computational modeling using finite element analys is as well as 3D computer-aided design tools to explore composition-structure-propertyperformance relations including microstructure , surface and interface connectivity, optical (UV/IR)curing and sintering conditions, etc. The technical approaches of this propose d research will be organized in four tasks to: (A) establish an advanced understanding of multiferroic composite nanomaterials and d evelop the computational capability to simulate and design targeted composites; (B) develop the nanomaterial inks by demonstrating t heir printability in professional grade hybrid 3D deposition systems and byfabricating and synthesizing in-situ; (C) establish mult i-materials hybrid deposition capabilities for direct fabrication (printing, curing and selective sintering) of multi-functional com ponents per design, combined with evaluation of their physical properties, and (D) tailor the H3D process, explore the dynamic contr ollability of the sensing and actuating functionalities, and demonstrate several selected application examples such as stacked piezo 1-3 energy converters, patterned magneto-elasto-electric core-shell composite devices, and polymeric ferroelectric multilayer compo sites including metal organic framework ferroelectric sensors.The research proposed will amass valuable experimental data in this gr owing area and develop the H3D fabrication of electroceramics capability addressing Navys needs in sensors and actuatorson demand. It will specifically advance understandings in acoustic wave interactions with nanostructured composites to guide the design and fa brication of smart sensors and actuators. Multiferroic nano-electroceramic-composites developed, can be an enabler for high performa nce actuators and sensors aimed at addressing the Navys needs in mobility and survivability for distributed forces
