The Surprising Science-And Medical Potential-Of Tattoos

Imagine glancing at your forearm for an immediate report on your current state of health. Thanks to engineers at the University of Texas, this technology may soon become a reality for hospital patients. They have created a wearable, disposable, heat-sensing, liquid crystal patch that tracks vital signs. Patients can wear this small device on their neck or forearm, and keep it there about for a week. This device will have the ability to monitor aspects of cardiovascular health that will be available for patients to see on a smartphone app: the app will decipher the colors of the patch and deliver a health report.
