Abstract

This paper demonstrates the dynamic stressing of viscous liquids in microfluidic channels. An infrared laser pulse is focused within the testing liquid in a microfluidic channel and a spherical shock wave near the interface is created. The shock is reflected by the free surface due to acoustic impedance mismatch. The displacement of the free surface in hundred nanoseconds is captured by a developed double-exposure optical system. The tensile strength can be estimated by using a series of results from different distances between the bubble and the free surface. This study has a great potential in the optical breakdown of biomaterials.
