Multigear Bubble Propulsion of Transient Micromotors

Figure 5

Fluid flow around Mg-TiO2 micromotors. The flow field generated by a (a) stationary and (b) motile Mg-TiO2 microengine. (i) is an instant of micromotor operation and (ii) illustrates the overlaps [34] of a stack of 50 fluorescent microscopy images (during a 4 sec period) to show the flow field around the micromotor.
