U of Texas E-tattoo enables accurate, uninterrupted heart monitoring for days
Researchers at the University of Texas at Austin have developed a new wearable technology made from stretchy, lightweight material could make heart health monitoring easier and more accurate than existing electrocardiograph machines.Led by Nanshu Lu in the Cockrell School of Engineering, this is the latest incarnation of Lu's electronic tattoo technology, a graphene-based wearable device that can be placed on the skin to measure a variety of body responses, from electrical to biomechanical signals, according to a university article.
The team published a paper about the research in a recent issue of Advanced Science.
The device is so lightweight and stretchable that it can be placed over the heart for extended periods with little or no discomfort, according to the article. It also measures cardiac health in two ways, taking electrocardiograph and seismocardiograph readings simultaneously. Seismocardiography (SCG) is a measurement technique using chest vibrations associated with heartbeats. Powered remotely by a smartphone, the e-tattoo is the first ultrathin and stretchable technology to measure both ECG and SCG
