In summer 2011, John Rogers - professor in Material Science at the University of Illinois - published a study in Science containing details of his ultra-thin electronic device which, while looking a tattoo, was capable of measuring a person’s heart rate and other vital signs.
The tattoo, which can be applied to natural skin without irritation and lasts for more than 24 hours, means a patient is freed from having to wear the type of bulky electrode normally used for hospital monitoring. More, it also increases the wearer’s mobility as they are able to monitor themselves without constant assistance from others.
Rogers said in his paper that he hoped the technology would be developed to help speed up the rate at which wounds, burns and other skin conditions heal and, ultimately, that it might replace other hospital adhesives.
A sign of the growing number of devices which are now able to monitor seamlessly various aspects of our lives.
