Materials Physics: Investigate the structure-property relationship; Characterize the structure and property; especially dielectric; electromechanical; and magnetostrictive properties; of polymers; ceramics and single crystals.; Smart/Adaptive Materials: Develop new smart materials: piezoelectric; ferroelectric; electro-optic; and dielectric ceramics and thin film; magnetostrictive thin film and nanowires; dielectric and multiferroic composites including nanocomposites; electroactive polymers (artificial muscle); Device Development: Design; fabricate and characterize novel micro/nano-sensor platforms; actuators and transducers; Develop biosensors for food safety and security.; Smart materials including piezoelectric; dielectric; ferroelectric; and magnetostrictive materials as well as their (nano)composites; Electroactive polymers (artificial muscle); Electromechanical actuators; transducers;and energy harvest device; Biological and chemical sensors. The goal is to investigate and simulate the physics behind the phenomena and to develop novel smart materials with high performance. The goal is to design, fabricate and characterize the devices, especially the micro/nano-devices, using smart materials.
