The history of tattoos has more than one millennium, and all this time, bizarre drawings on the human body reflected either his social status, or an irrepressible desire to look different from everyone else. Recently, however, the tattoo has seriously interested scientists working in the field of nanotechnology.
A group of researchers at the University of Pennsylvania (USA), headed by Professor Brian Litt, is developing a technology for implanting nanoelectronic modules on a silk carrier under the human skin. The idea of the developers is that after some time the implanted implant will partially dissolve under the skin, with the exception of the electronic filling. Due to its miniature size, it will not cause discomfort to the owner.
The implant is based on silicon-silk LED self-absorbable threads 1 mm x 250 nm (length, thickness), which are widely used in surgery. The plans of Professor Litt and his colleagues are to create an electronic tattoo in the form of an LED screen, where, for example, sugar level, pulse, blood pressure and other indicators of the human body will be displayed.
