Tattoos made from patches of tiny needles can permanently encode complex medical information directly onto the skin and provide a means to constantly monitor physiological changes to the body.
The microneedle patch tattoos were able to imprint numbers, letters and symbols onto animal skin, thereby offering the potential to indelibly create medical alerts for conditions such as diabetes or imprint QRS codes to carry other vital health information.
