Mechanics of Soft Filaments: From Biology to Engineering
ORAL · Invited
Abstract
Filaments of soft materials such as rubber and biopolymers can undergo large complex deformations under external stimuli. Soft filaments offer exciting applications in engineering, life science, and medicine since their nonlinear conformational changes can be harnessed for robust functional mechanisms. Understanding the spatiotemporal deformation and energetics of soft filaments is fundamental to advancing future engineering and medical applications. This presentation will discuss the mechanics of two fascinating soft filaments: 1) protein filaments forming the contractile injection machinery of the virus bacteriophage T4, and 2) photo-responsive filaments proposed for future wireless soft robotics. I will showcase how principles of applied mechanics can advance the understanding, analysis, and design of soft filaments in applications ranging from biology to engineering.
