Berlin scientists and tattooists are working together on biotech tattoos that change color depending on health conditions such as blood sugar or dehydration. These functional tattoos are intended to act like wearable medical devices, merging aesthetics with health monitoring.
German universities are supporting research that could revolutionize both medicine and body art. While still in clinical trials, these tattoos could one day save lives by alerting wearers to dangerous health changes, proving tattoos can be practical as well as expressive.
