Reconstructed Attractor for Life State Detection
This study evaluates physiological states of organisms from a nonlinear system perspective. Taking the human body as an example, the running states of heart and blood vessels are obtained by collecting ECG and PPG signals, and the feature extraction of complex physiological signals is applied by chaotic attractor reconstructions. Digital life state monitoring will provide…

Mental Stress Assessment in Daily Life Using Electrocardiogram and Pulse Wave
It is believed that quantification and monitoring of daily stress can lead to prevention of various stress-related diseases. In this study, we integrated simultaneously measured electrocardiograms and pulse waves to calculate highly accurate stress values that are not easily affected by noise, and calculated the reliability of each biological signal in a defined analysis interval…

Simultaneous measurement of contractile force and field potential of dynamically beating human iPS cell-derived cardiac cell sheet-tissue with flexible electronics
Human-induced pluripotent stem (iPS) cell-derived cardiomyocytes are widely employed in global in vitro studies for both pharmacological and pathological research. Specifically, evaluating the functionality of heart tissues generated from these iPS cell-derived cardiomyocytes holds the promise of accurately predicting the effects of drugs, thereby streamlining the drug development process. Nevertheless, the existing method of assessing…

Wearable Electronics: Smart Face Mask Based on an Ultrathin Pressure Sensor for Wireless Monitoring of Breath Conditions
Deaths from sudden cardiac disease have been at a high level among causes of mortality during the past ten years, according to WHO statistics. Long-term ECG monitoring of the human body is frequently necessary for the approach of preventing and treating sudden cardiac illness. Many diseases, including sudden cardiac disease, will lead to minor alterations…
