Temporary tattoos could be used to monitor your health, thanks to work done by researchers at the University of Toyko.

Scientists have developed a flexible sensor that looks exactly like a temporary tattoo — but is a lot more useful. The sensors are developed to monitor a patient's vital signs, with scientists hoping they'll be able to replace the often uncomfortable plastic ones currently in use.

Those with chronic health issues will be the main beneficiaries of the technology, but pregnant women and athletes who need to track their vitals would also benefit from the breakthrough.

The hypoallergenic sensors are made of nanoscale mesh and are designed not to irritate the wearers' skin, all the while withstanding daily usage and monitoring touch, temperature and pressure.

While the tattoo sensors won't be officially introduced anytime soon, their development indicates that we can look forward to a more comfortable — and aesthetically pleasing — healthcare future.
