This work reports a self-powered pulse sensor based on cellular piezoelectret with high sensitivity to record pulse waveforms and reveal sinus arrhythmia as a practical medical microsystem. The high ...

At their core, sensors convert real-world stimuli—temperature, motion, pressure, light, proximity, and more—into measurable ...

Timely detection of abnormal pulse wave conditions can provide early warnings for cardiovascular emergencies. Strain sensors can detect subtle pulse wave changes, however, they often face a trade-off ...

Artificial intelligence (AI) is playing a huge role in heat rate optimization. In some cases, AI-driven models have analyzed ...
