    Elastocapillary Dynamics in Soft Gels

    Soft gels are utilized in emerging applications, e.g. bioprinting, and are distinguished in that the forces of capillarity (surface tension) and elasticity are comparable in magnitude leading to elastocapillary phenomena including the observation of new analogous hydrodynamic instabilities in soft materials. This talk will provide a survey of our recent work in this area including gel drop oscillations in ultrasonic levitation, soft fracture, splash suppression, and droplet durotaxis. In each example, we highlight the multiphysics through the elastocapillary number and viscoelastic relaxation time scale. Of particular note is that our results can be used as novel diagnostic techniques to measure the surface tension and fracture energy of soft gels.
