SciCafe: Engineering Technologies Inspired by Nature

Wednesday, November 7, 2018

Mechanical engineer Tak-Sing Wong draws inspiration from the natural world for his technological inventions. From the slippery rims of Nepenthes pitcher plants, Wong was inspired to create a material capable of repelling liquids and preventing bacteria from adhering. And he looked to the biological process of phagocytosis—when a cell engulfs and consumes another—to invent a self-healing surgical film to treat the surfaces of medical devices. Learn about the wide range of possible applications for these new materials.

 

 

 

About the Speaker

Headshot of Tak-Sing Wong

Tak-Sing Wong is an Assistant Professor of Mechanical Engineering and Biomedical Engineering, and Head of the Laboratory of Nature Inspired Engineering at The Pennsylvania State University. His research group develops biologically inspired materials with applications in health, energy, and water sustainability. His group’s research innovations range from the development of Nepenthes pitcher plant-inspired slippery surfaces that repel almost everything, to the discovery of camouflage function of leafhopper-produced brochosomes, to the creation of self-healing reverse filter inspired by the biological process of phagocytosis. He was named one of the world’s top 35 Innovators Under 35 by MIT Technology Review for his contributions in biologically inspired engineering.
