Dynamic materials comprising of soft solids and structured liquids that can adapt to surrounding environment are poised to be key components of future technologies. They offer the unique opportunity couple changes in their mechanical confirmation to physical properties and function via their micro and nano scale architecture. However, soft and fluid materials are seldom used for optical engineering. Here I will discuss the development of multi-phase fluid emulsions for dynamic optics and how we can engineer them to serve as both optical actuators and sensors by setting up microscopic tug-of-war battles with swimming bacteria.

Dr. Hari Vijayamohanan earned a M.Sc. in Chemistry and a B. Tech. in Electrical Engineering from the Birla Institute of Science and Technology Pilani, India and a Ph.D. in Materials Engineering from RPI. As a graduate student he worked in the group of Prof. Chaitanya Ullal developing optical lithography strategies that circumvent the diffraction limit. Subsequently he was a postdoctoral associate in the Department of Chemistry at MIT working in the group of Prof. Timothy Swager. His research interests include the development of strategies for precision actuation and sensing of mechanical forces at the mesoscale and the design of dynamic sensors and actuators for inaccessible interfaces.
