There are many applications in health care, wellness, and fitness. These tattoos can gather electrophysiological information which connects electrical activity to physiological functions such as brain activity, heart rate, respiration, and so on. The sensor, when mounted on the throat for example, can utilize data collected in conjunction with pattern recognition software that can work as an interface to technology and assist those with larynx disorders. Premature babies often need to be monitored for appropriate breathing and heart rate. A wireless tattoo would make it that much easier to ensure the baby’s safety rather than hardwiring the infant. These tattoos may also aid with physical rehabilitation not just as monitors, but also as a device to stimulate muscle contractions without restraining motion.
