Wireless, Wearable ECG Device
June 14, 2022 | Terry Sharrer
“This study develops a breathable, stretchable sensor sheet by employing a kirigami structure, and we [engineers at Osaka Prefecture University, Japan] examine the size dependence of electrocardiographic sensors. Because the kirigami film has many holes, sweat readily passes through the sensor from the skin to the environment. . . . . The limitation of the size is studied in relation to the signal-to-noise ratio of electrocardiographic signals, even under exercise. We found that the optimal size of the sensor is ∼200 mm2 and the distance between electrodes is 1.5 cm. Finally, long-term wireless electrocardiographic monitoring is demonstrated using data transmission to a smart phone app during different activities.” MORE
