Soft Interfaces: From Microfluidics to Kitchen

Abstract Living matter, from plants and animal cells, comprises complex materials with various phases and interfaces. A close look at how these soft interfaces arise and form certain shapes with functions will not only deepen our understanding of nature but also inspire the design and engineering of materials for novel applications. In this talk, I will first introduce hydrodynamic synchronization, which can be observed in swimming organisms, and explain how hydrodynamically interacting fluid-fluid interfaces can act as coupled oscillators leading to the discovery of a synchronized droplet generation. Second, I will present methods to fabricate nature-inspired shapes of microstructure to provide multifunctionality to the material, such as wrinkles on curved surfaces and multi-compartment microfibers, by exploiting oil-water interfaces. Lastly, I will investigate biological cells as soft matter to study the dependence of their motility on the geometry of cells and confinements as in complex tissue environments. We can even use materials found in our kitchen to understand the physicochemical roles of complex fluids in determining the shapes and motility of nature. My ultimate research goal in soft interfaces is to apply the knowledge from complex fluids experiments to emerging technologies of biomedical applications....

Bi-directional neural interfacing & electroceuticals based on flexible electronic devices for treating neurological disorders

Realizing a clinical-grade electronic medicine for peripheral nerve disorders is challenging owing to the lack of rational material design that mimics the dynamic mechanical nature of peripheral nerves. Specifically, long-term stability of devices interfacing peripheral nerves is challenging, since dynamic mechanical deformations in peripheral nerves...
