Rational Design and Additive Manufacturing of 3D Piezoelectrics with Arbitrary Anisotropy for Maritime Self-Sensing Structures and Transducers
Abstract
The YIP PI Dr. Zheng will develop theoretical and numerical calculation methods that involve assemblies and manipulations of parametrized piezo-active unit cells to inversely design piezoelectric anisotropy, making it possible to access previously unattainable regimes of the piezoelectric tensor space. He will then formulate highly concentrated and functionalized perovskite-based, light-sensitive feedstock. This piezoelectric feedstock will then be optically patterned into complex threedimensional micro-architectures and form-factors, building on an AM method previously developed by the Dr. Zheng. Dr. Zheng will investigate the unique functional and structural properties of these types of 3D structured piezoelectrics and evaluate their use for underwater and in-air sensing capabilities.
