Surface tension biomimetics need to have a transplant or repair performed. Microvelia exploit surface tension by creating a surface tension gradient that propels them forward by releasing a surfactant behind them through a tongue-like protrusion. Biomimetic engineering was used in a creative and fun way to make and edible cocktail boat that mimicked the ability of microvelia to propel themselves on the surface of water by means of a phenomenon called the marangoni effect. Burton and her colleagues used 3D printing to make small plastic boats that released different types of alcohol behind the boat to lower the surface tension and create a
Surface tension be the same for all shapes. We therefore define the surface tension as The reason for the is that the film has two sides, each of which contributes equally to the force; so the force contributed by a single side is . In terms of energy: surface tension of a liquid is the ratio of the change in the energy of the liquid, and the change in the surface area of the liquid (that led to the change in energy). This can be easily related to the previous definition in terms of force: if is the force required to stop
