3D print technology is constantly making new leaps. Nearly daily 3D printers are present who can build entire houses until they are placed on human skin sensors. Such a printer was created by researchers from the University of Minnesota.
This $ 400 printer “prints” on human skin sensors in a way similar to the tattoo. Applications are unlimited since all kinds of sensors can be mounted. For example, soldiers can place sensors on their hands to detect chemical or biological weapons.
Human cells can be placed on the skin through the printer with biological cells that will have various kinds of medical functions such as wound healing. When finished, the sensors can be removed easily either by removing them with a tweezer or even with water.
