German scientists came up with dermal sensors that can be infused into human skin instead of tattooing ink that changes its color according to one’s blood pH, sugar and sodium levels, allowing for the person’s health to be tracked without ever visiting a doctor’s office.

This new discovery could be really useful for people who constantly need to have their blood samples taken, for example, the ones with diabetes or kidney illnesses. Therefore, glucose indicators in these tattoos could be particularly helpful for them as it changes color from yellow to dark green depending on the patient’s blood sugar levels.

Using this new invention instead of regular tattoo ink offers an advanced way to care for your health by having an aesthetically pleasing decoration on your skin that can be made completely personal and wouldn’t be associated with your health by others, therefore giving you the advantage of keeping it discreet.

As on this day, it has only been tested on pig skin that is commonly used for practice by tattoo artists. Hopefully, it will soon be acknowledged as safe for human use and will make the lives of many people a lot easier and healthier!
