Cardiovascular disease remains one of the leading causes of mortality worldwide. Early detection and continuous monitoring through signals like ECG, heart sounds, and pulse play a crucial role in preventing serious health complications. Recently, a team led by Li Zhou from the Beijing Institute of Nano Energy and Systems, Chinese Academy of Sciences, and Wang Zhonglin, a foreign academician of the Chinese Academy of Sciences, collaborated with experts from Beijing Anzhen Hospital and Chaoyang Hospital to create a groundbreaking solution: a self-powered, ultra-sensitive pulse sensor that enables Bluetooth-based wireless transmission for cardiovascular diagnostics—without the need for external signal amplification.
Pulse sensing is one of the most commonly used technologies in medical monitoring, yet traditional sensors still face significant challenges in terms of sensitivity, signal-to-noise ratio, power consumption, and cost. The newly developed device overcomes these limitations by directly converting pulse vibrations into an electrical signal of up to 1.52 volts. Its signal-to-noise ratio is ten times higher than that of conventional photoelectric pulse sensors, while its cost is only one-fifth of existing alternatives. By integrating the sensor with a Bluetooth module, it allows real-time wireless transmission of pulse data to smartphones or computers, enabling users to monitor and analyze their heart health conveniently.
In a clinical trial, the system was tested on both healthy adults and patients, successfully identifying arrhythmias such as atrial fibrillation and differentiating between conditions like coronary heart disease and atrial septal defects. This represents a major breakthrough, as it is the first study to demonstrate the feasibility of using triboelectric nanogenerators for self-powered cardiovascular diagnosis. The research opens new possibilities for mobile and intelligent healthcare systems, offering a more affordable, efficient, and accessible approach to heart disease monitoring.
The findings were recently published in *Advanced Materials*, marking a significant step forward in wearable biomedical technology. With further development, this innovation could revolutionize how individuals manage and track their cardiovascular health on a daily basis.
