On shape control : some case studies inspired by biological and bio-inspired locomotion at small scales
Control of shape is at the root of many processes of fundamental relevance in Biology, from morphogenesis to locomotion.
For slender one-dimensional objects (rods) or thin two-dimensional ones (plates and shells), shape can be controlled by adjusting curvature thanks to the application of active internal stresses. These may result from biological agents (molecular motors), from spontaneous distortions triggered
by phase transitions, from swelling due to solvent absorption, from growth or thermal
distortions, etc.
We will report on a few case studies, inspired by biological locomotion (undulating snakes, metaboly in euglenids, which is a family of unicellular swimmers), in which the problem of shape control is first analysed through mathematical models, and then reproduced in simple desk-top experiments.
The audience is composed of people with rather heterogeneous backgrounds including specialists in solids, fluids, granular flows, statistical physics... so the idea is to keep your talk understandable by people not necessarily working in your field... The seminar time slot runs from 11am to noon so the best is to make the talk last around 45 minutes to leave some time for discussion.
