Abstract
Currently, many technology innovations have advanced piezoelectric materials and composites toward a broad range of biomedical applications. In this talk, I introduce our most recent development of piezoelectric materials and composites that are particularly designed for implantable nanogenerator applications. First, I present our wafer-scale approach to creating piezoelectric biomaterial thin films based on γ glycine crystals. The self-assembled sandwich film structure enabled both strong piezoelectricity and largely improved flexibility. Then, new ferroelectric composites are presented as a new material used in 3D printing for directly manufacturing of piezoelectric architectures with tunable piezoelectric and mechanical properties. Toward the end, development of implantable nanogenerator devices are introduced, including biocompatibility, degradability and packaging. This type of devices enables new capability of in vivo charging and electrostimulations, which revolutionaries the design and implementation of many biomedical therapeutics.
