"We can get much greater insight into heart health by the synchronous collection of data from both sources," said Lu, an associate professor in the departments of aerospace engineering and engineering mechanics and biomedical engineering.ĮCG readings alone are not accurate enough for determining heart health, but they provide additional information when combined with SCG signal recordings. Powered remotely by a smartphone, the e-tattoo is the first ultrathin and stretchable technology to measure both ECG and SCG.
Seismo-cardiography (SCG) is a measurement technique using chest vibrations associated with heartbeats.
Most of us are familiar with the electrocardiogram (ECG), a method that records the rates of electrical activity produced each time the heart beats. It also measures cardiac health in two ways, taking electrocardiograph and seismo-cardiograph readings simultaneously. The device is so lightweight and stretchable that it can be placed over the heart for extended periods with little or no discomfort.

It could make heart health monitoring easier and more accurate than existing electrocardiograph machines – a technology that has changed little in almost a century.ĭeveloped by engineers at The University of Texas at Austin and 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 bio-mechanical signals. A new wearable technology developed at the University of Texas and made from stretchy, lightweight material measures cardiac health by taking electrocardiograph and seismo-cardiograph readings simultaneously.
