Due to this ‘repulsive force,’ the droplet hovers over the surface rather than making physical contact with it.

A key modern breakthrough in the control of Leidenfrost drops was the discovery (Linke et al. 2006) that a surface with parallel asymmetric ridges will act as a ratchet, propelling the drops in the direction toward the steeper sides of the ridges, an effect that has been attributed to the flow features underneath deformed drops.

A Brownian heat engine is a system that rectifies the flow of Brownian particles to transform local temperature variations into directed motion (work). In the context of electronics, this is the principle of thermoelectric energy conversion.

This is most commonly seen when cooking, when a few drops of water are sprinkled in a hot pan. If the pan's temperature is at or 2006-06-10 · Title: LEIDENFROST RATCHETS Approved: ˙ Dr. Heiner Linke A “Leidenfrost ratchet” is a device which facilitates a newly-discovered phenomenon, where drops of liquid accelerate across a heated substrate. The system has been qualitatively studied and a vapor flow model has been suggested to account for this observed behavior. 2015-01-01 · Recently, the Leidenfrost effect has been subject to a renewed interest following the discovery by Linke et al. (2006). Placed on an asymmetrically structured surface (called a ratchet), Leidenfrost drops can self-propel in a preferential direction with velocities of the order of 10 cm s −1 .

The system has been qualitatively studied and a vapor flow model has been suggested to account for this observed behavior. A leidenfrost droplet forms when a liquid droplet is placed on a very hot surface. In the case that there is a thin layer of insulating material as a step on the substrate, under specific conditions Leidenfrost droplets interact with the edge of the step.

In the context of electronics, this is the principle of thermoelectric energy conversion.
This may include (but is not limited to) surface roughness, contamination in the liquid, and the amount of wetting between the surface and the non-suspended liquid. This effect works until a much higher temperature causes any further drops of water to evaporate too quickly to cause this effect. This is because at temperatures above the Leidenfrost point, the bottom part of the water droplet vaporizes immediately on contact with the hot plate.
