A defining feature of living organisms lies in their efficient use of surfaces to dynamically interface with environments for a continuous flux and exchange of water, energy, heat, and information. The ubiquity and diversity of these elegant natural surfaces construct the Surface of Things (SOT), reminiscence of Internet of Things (IOT) which has received vast attention and widely penetrated into our daily life. Despite extensive progress, particularly triggered by learning from nature, the power and magic of natural surfaces evade our deep scrutiny, and it also appears challenging to design, manufacture and adopt artificial SOTs that exhibit high performances as their natural counterparts. The challenges originate from the complexity in adopting one surface design to resolve many seemingly contradictory properties to yield optimized functions for many practical applications, especially in harsh environments.
In this talk, I will reveal intriguing property-function relationships on natural surfaces and then design, manufacture nature-inspired SOT with tailored complementary properties in topography, wetting, thermal/electrical conductivity, stiffness to overcome the inherent tradeoff otherwise associated with homogeneous design for water, energy, environment and healthcare applications.
