This Photoacoustic Watch takes pictures of Blood Vessels

Pioneering researchers at the Southern University of Science and Technology have unveiled a groundbreaking wearable device poised to revolutionize health monitoring. Dubbed the “Photoacoustic Imaging Watch,” this marvel of innovation combines cutting-edge technology with portability, offering a non-invasive means to track vital health metrics such as heart rate, blood pressure, and oxygen saturation.

Utilizing photoacoustic imaging, the watch captures high-resolution images of blood vessels beneath the skin, providing invaluable insights into cardiovascular health. Unlike traditional hospital equipment, this portable device frees users from stationary constraints, enabling them to monitor their well-being on the go.

At the heart of this technological marvel lies a sophisticated interplay of light and sound waves. A specialized laser beam, delivered via fiber optic cable, penetrates the skin to illuminate internal structures. As the light is absorbed, it generates faint sound waves, which are then captured by the watch’s built-in microphone. This dual-functionality not only allows for visual imaging but also facilitates auditory assessment, potentially alerting medical personnel to any cardiac irregularities.

The research team, comprised of Lei Xi, Ting Zhang, Heng Guo, and Weizhi Qi, has conducted rigorous testing to validate the watch’s efficacy. Trials with volunteers have demonstrated its ability to detect blood flow changes over extended periods, even under diverse conditions. Encouraged by these results, the researchers are now focusing on refining the device further, aiming to enhance its compactness, safety, and resolution.

Looking ahead, the team envisions a future where advancements in laser diode and electronic information technologies render bulky backpacks obsolete. With plans to stabilize the optical path and introduce a spectrum of lights for enhanced imaging capabilities, they are poised to unlock new frontiers in wearable health monitoring.

In the words of lead researcher Lei Xi, “Given the rapid development of modern technology, it should be entirely feasible to develop a more advanced and intelligent photoacoustic watch.” As the boundaries of innovation continue to expand, this remarkable device promises to empower individuals with unprecedented insights into their health, all from the convenience of their wrist.
