The biomechanics of a tattoo is a "demonstration" of the internal organs of a person, supplemented or replaced by mechanical elements with microcircuits, gears, wires and other details. The idea of this style is borrowed from the movie "Alien", and the name means a combination of living matter with mechanisms.

A tattoo in the style of biomechanics looks especially impressive when applying a drawing in 3D technology. Due to the combination of three-dimensionality and hyperrealism photo of a tattoo, where metal structures are visible under the torn skin, makes an indelible impression.

It is the "torn skin", which is the main technique of the organic style, that unites these two directions (organic is considered a kind of biomechanics). They are also similar to each other in the image method, color scheme and rather large drawing sizes. But organics differs in that the flesh in it connects with living nature, and not with mechanisms. It is less gloomy and not so aggressive.

Choosing a sketch of a tattoo in the style of biomechanics, girls usually prefer colored organic materials. A men choose black-and-gray images with various mechanisms under roughly torn skin.
