Self-propelling phenomenon that the corresponding device can move on water surface without external energy input has prospective applications in different fields including cell and bacterial control, medical transportation and drug delivery.However, the current strategies to propel the microdevices have Noodlies many problems which extremely limit their promotion.Here, we reported a self-propelling miniboat composed of a superhydrophobic plate and a superhydrophilic wedge-shaped pattern on its surface to realize the conversion of the surface energy of the water droplet to the kinetic energy of the miniboat.A water droplet dropped on the wedge-shaped pattern easily transported and immersed in water, providing enough force to propel the miniboat.Moreover, the displacement and velocity of the miniboat can be controlled by adjusting the water droplet volume.

This study has an important scientific significance and value for promoting the practical application of the self-propelling phenomenon Travel Essential on water surface.
