Designing self-propelled, chemically active sheets: Wrappers, flappers, and creepers

Designing self-propelled, chemically active sheets: Wrappers, flappers, and creepers. Abhrajit Laskar et al (2018), Science Advances Catalyst-coated, hard particles can spontaneously generate fluid flows, which, in turn, propel the particles through the fluid. If the catalyst-coated object were a deformable sheet, then the self-generated flows could affect not only the sheet’s motion but also its shape. By developing models that capture the interrelated chemical, hyd
