Researchers from China’s Southern University of Science and Technology have developed a werable photoacoustic imaging watch that lets you see the blood vessels in your skin in real-time. The system consists of a watch with an imaging interface, a handheld computer and a backpack housing the laser as well as power supply.
What could such a system be used for? Health centers can use it to preliminary diagnose diseases or for long-term monitoring of parameters related to blood circulation within a hospital setting. Future versions could even be used for early detection of skin conditions such as psoriasis or melanoma and also to analyze burns. Photoacoustic imaging basically measures light-induced sound waves created by light absorption in structures.

Although photoacoustic imaging is extremely sensitive to variations in hemodynamics, difficulties in miniaturizing and optimizing the imaging interface have limited the development of wearable photoacoustic devices. To the best of our knowledge, this is the first photoacoustic wearable device that is suitable for healthcare applications,” said Lei Xi, research team leader from the Southern University of Science and Technology in China.
