The progress of humankind has been marked by five main waves of innovation. Each wave has transformed our industries and societies, yet is also coupled with the consumption of resources, pollution, and energy/water shortage. In contrast, honed by billion years’ evolution, nature has developed extraordinary principles which are characterized with green energy and resilience.
This talk focuses on how the rational control of topological effect, which is normally overlooked in the conventional engineering domains, will fundamentally change the fluid and thermal transport and trigger new applications. In particular, I will discuss our recent progress in the exploration of nature-inspired topological structures for various implementations such as droplet based electricity generation, directional water transport and harvesting, soft robotics as well as reversible adhesion (1-5).
