Dominik J. Bell, Stefan Leutenegger, K. Magnus Hammar, Flagella-like Propulsion for Microrobots Using a Nanocoil and a Rotating Electromagnetic Field Dominik J. Bell, Stefan Leutenegger, K. Magnus Hammar, Lixin Dong, and Bradley J. Nelson Institute of Robotics and Intelligent Systems, ETH Zurich, CH-8092 Zurich, Switzerland First imitation of helical, bacterial flagella at the same size scale as natural flagella Bilayer nanocoil propeller with small Ni plate “head” attached to one end Rotation of nanocoil is induced by a rotating electromagnetic field using macro coils Rotation results in net axial force due to low Reynolds number flow
