Anti‐Motion Artifacts Iontronic Sensor for Long‐Term Accurate Fingertip Pulse Monitoring

Advanced Science, EarlyView.
Flexible pressure sensors are essential for pulse monitoring and cardiovascular disease diagnosis but are affected by motion artifacts (MAs) due to stretching stress. The S‐smooth sensor with a soft‐hard stretchable interface that dissipates energy, reducing MAs by 90% is developed.

Qualitative transcriptional signatures for evaluating the maturity degree of pluripotent stem cell-derived cardiomyocytes

Stem Cell Research & Therapy, 2019
Background Pluripotent stem cell-derived cardiomyocytes (PSC-CMs) are widely used models for regenerative medicine and disease research. However, PSC-CMs are usually immature in morphology and functionality and the maturity of PSC-CMs could not be ...

Physical Reservoir Computing for Real‐Time Electrocardiogram Arrhythmia Detection Through Controlled Ion Dynamics in Electrochemical Random‐Access Memory

Advanced Electronic Materials, EarlyView.
This study presents an ECRAM‐based physical reservoir computing system for real‐time electrocardiogram arrhythmia detection. By optimizing electrolyte ionic conductivity and channel ionic diffusivity, it achieves including non‐linear dynamics, millisecond‐scale tunable retention, low‐power operation, and minimal variation.
