Contribution
It presents a new micro-swimmer design inspired by protozoan metaboly, showing improved efficiency in low Reynolds number environments.
Findings
Demonstrates higher swimming efficiency than previous models
Uses shape change resembling protozoan metaboly
Effective at low Reynolds numbers
Abstract
The swimming of a pair of spherical bladders that change their volumes and mutual distance is efficient at low Reynolds numbers and is superior to other models of artificial swimmers. The change of shape resembles the wriggling motion known as {\it metaboly} of certain protozoa.
