报告简介：

　　This seminar covers our group’s recent work on novel 2D nanomaterials development and mechanical energy harvesting device innovations. In the first half, I will present an ionic layer epitaxy (ILE) technique that uses surfactant monolayers to serve as soft templates guiding the nucleation and growth of 2D nanomaterials in large area beyond the limitation of van der Waals solids. Through this approach, 1 to 2 nm thick, single-crystalline free-standing ZnO nanosheets with sizes up to tens of microns were synthesized at the water-air interface. So far, we have showed successful synthesis results from ZnO, CuO, and CoO, MnO2. ILE vastly broadens the range of 2D nanomaterials from layered van der Waals solids to oxide ceramics, opening up opportunities for discoveries of exciting transport, magnetic, photonic, and catalytic properties. In the second half, I will present our developments of wearable and implantable bioelectronic devices that harvest biomechanical energy and convert it into electric stimulations for medical treatments.   Both results bring a new concept in electrical therapeutic technology that is battery-free, self-activated and directly responsive to body activities.
