The leading cause of death in Texas is heart disease, according to the National Center for Health Statistics, accounting for more than 45,000 deaths statewide in 2017. A new wearable technology made from stretchy, lightweight material could make heart health monitoring easier and more accurate than existing electrocardiograph machines — a technology that has changed little in almost a century.
Developed by engineers at The University of Texas at Austin and led by Nanshu Lu in the ラーメンベット 禁止ゲーム of ラーメンベット 入金不要ボーナス 出金条件, 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.
The ラーメンベット 入金不要ボーナス 出金条件 team reported on their newest e-tattoo in a recent issue ofAdvanced Science.
The device is so lightweight and stretchable that it can be placed over the heart for extended periods with little or no discomfort. It also measures cardiac health in two ways, taking electrocardiograph and seismocardiograph readings simultaneously. Most of us are familiar with the electrocardiogram (ECG), a method that records the rates of electrical activity produced each time the heart beats. 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.
“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 ラーメンベット 入金不要ボーナス 出金条件 and ラーメンベット 入金不要ボーナス 出金条件 Mechanics and Biomedical ラーメンベット 入金不要ボーナス 出金条件.
ECG readings alone are not accurate enough for determining heart health, but they provide additional information when combined with SCG signal recordings. Like a form of quality control, the SCG indicates the accuracy of the ECG readings.
Although soft e-tattoos for ECG sensing are not new, other sensors, such as the SCG sensor, are still made from nonstretchable materials, making them bulky and uncomfortable to wear. Lu and her team’s e-tattoo is made of a piezoelectric polymer called polyvinylidene fluoride, capable of generating its own electric charge in response to mechanical stress. The device also includes 3D digital image correlation technology that is used to map chest vibrations in order to identify the best location on the chest to place the e‐tattoo.
The e-tattoo has another advantage over traditional methods. Usually an ECG measurement requires going into a doctor’s office, where heart health can be monitored only for a couple of minutes at a time. This device can be worn for days, providing constant heart monitoring.
Lu and her team are already working on improvements to data collection and storage for the device, as well as ways to power the e-tattoo wirelessly for longer periods. They recently developed a smartphone app that not only stores the data safely but can also show a heart beating on the screen in real time.
Lu’s team includes faculty members and students spanning multiple ラーメンベット 入金不要ボーナス 出金条件 disciplines — aerospace ラーメンベット 入金不要ボーナス 出金条件 and ラーメンベット 入金不要ボーナス 出金条件 mechanics, biomedical ラーメンベット 入金不要ボーナス 出金条件, electrical and computer ラーメンベット 入金不要ボーナス 出金条件, materials science and ラーメンベット 入金不要ボーナス 出金条件, and mechanical ラーメンベット 入金不要ボーナス 出金条件, as well as a collaborator from UT Southwestern Medical School. In addition, at the time the research was conducted, four members of the UT Austin team were undergraduate students.
The ラーメンベット 入金不要ボーナス 出金条件 was funded by the Office of Naval ラーメンベット 入金不要ボーナス 出金条件, the Air Force Office of Scientific ラーメンベット 入金不要ボーナス 出金条件, the National Science Foundation and the National Institutes of Health.
