Free surface propulsion by electrowetting-assisted ‘Cheerios effect’

This paper presents how “Cheerios effect” is combined with EWOD (electrowetting on dielectric) in order to propel floating objects. Cheerios effect is a common phenomenon in which small floating objects are either attracted or repelled by the sidewall. This behavior is known to be highly dependent on the hydrophobicity of the walls. By electrically… CONTINUE READING
