Flower-shaped Micromotors Driven by Gliding Bacteria


A flower-shaped micromotor driven by gliding bacteria named Mycoplasma mobile (M. mobile) has been developed by using two-photon microfabrication. This micromotor is autonomously rotated by the collisions of M. mobiles gliding randomly on a substrate. The flower-shaped rotor is derived from the unique motility of M. mobile. We examined the motility characteristics of M. mobile using walls with different corner angles. As a result, we found that M. mobile kept going at cusps. Owing to this property, the microrotor can be continuously rotated by random collisions of M. mobiles. The bacteria-driven micromotor will be applied to self-powered microsystems.
