Abstract

An in-situ poled ferroelectric prints with true 3D geometry is provided with an intercalated electrode design where soft polymer matrixes are selected for the ferroelectric layers, and rigid polymer matrixes are selected for the electrode layers, thus mimicking nacre architecture with a ceramic-like piezoelectric property and bone-like fracture toughness. Lithium-doped potassium sodium niobite (Li—KNN) microparticles may be used to produce ferroelectric properties and to create strong interfacial bonding with the interfacing electrode layers. Polylactic acid (PLA) in the electrode layers may be used to facilitate strong interfacial bonding with the Li—KNN microparticles.
