1. A tattooing apparatus, comprising:
a needle having at least one tip, wherein the needle is configured to move between a first position in which the tip is located above the surface of a skin, and a second position in which the tip is located at a penetration depth underneath the skin surface, and wherein the needle is further configured to deposit an ink between the skin surface and the penetration depth; a needle drive mechanism configured to move the needle between the first position and the second position; a sensor configured to output a feedback signal corresponding to a skin thickness characteristic, wherein the skin thickness characteristic includes a detected depth and thickness of a dermis layer of the skin, wherein the dermis layer of the skin has a fluctuating detected depth and thickness; and a controller configured to receive the feedback signal, wherein the controller is configured to automatically adjust the penetration depth based on the skin thickness characteristic to account for the fluctuating detected depth and thickness such that the ink is deposited at a specified depth within the dermis layer of the skin, wherein the specified depth is a consistent percentage of the thickness of the dermis layer of the skin. |
