Microflow manipulation for actuation, sensing and manufacturing
This talk will discuss several approaches to manipulating microflows including thermally responsive fluids that reversibly solidify at elevated temperature and that are liquid at low temperature. These materials can be used for valving in microfluidic channels and to control micromanipulators. Evaporation-driven flows allow the controlled deposition of particles on substrates or the deposition of a polymer layer from a solution in a solvent casting process to form microstructures. This process facilitates the fabrication of microneedles for medical applications such as intradermal injections and biosensing.
