University of Texas researchers have created a technique in producing high-performing yet inexpensive wearable patches which can be worn to monitor and track the vital signs of the body. Their devices are capable of picking up and transmitting these vital signs while it can also keep track of heart rate, muscle movement, brain activity, temperature and hydration levels.
Tests revealed that these wearable patches have picked up signals from the body stronger than the existing medical devices which includes ECG/EKG. It is a very thin and reliable device that will stick to the skin much like a temporary tattoo. The process in creating these patches begins and ends using inexpensive materials, which the researchers believe may lead to roll-to-roll manufacturing in the future.
