Cardiovascular disease is the world's leading cause of death. According to the World Health Organization, 17.9 million people die every year due to cardiovascular diseases. For the prewarning and accurate treatment of cardiovascular diseases, it is important to monitor hemodynamic parameters continuously, including blood pressure (BP), heart rate (HR), peripheral resistance (PR), and vascular elasticity.
Soft wearable devices are well suited to monitoring physiological signals such as electrocardiogram signals, phonocardiogram signals, and pulse waves with the advantages of real-time operation capability, skin-like mechanical properties, and high-SNR sensing capability. However, the human cardiovascular system is complicated and distributed with network circulation.
The distributed optical fiber sensing technique represented by the fiber Bragg grating is ideally suited for spatiotemporal hemodynamic monitoring. Its spatially distributed multichannel sensing capability, excellent temporal synchronization and lack of electromagnetic interference lay a foundation for multiple high-SNR physiological signal monitoring.
Flexible packaging technology has been used to address the mechanical mismatch. Nevertheless, excessive thick encapsulation and the low sensitivity of commercial FBG devices pose an obstacle in detecting subtle physiological signals, thereby limiting their potential applications in wearable devices. The technique employs microfiber and ultra-thin flexible packaging technology to prepare skin-like microfiber patches. By effectively reducing the equivalent modulus of the device and the cross-sectional area of the microfiber, the stress response of the patch is improved by two orders of magnitude . It also shows great repeatability and stability under 10,000 stress circles.

New research expands insights into most adequate treatment for uterine descentWhen uterine descent requires surgery, various procedures exist. A randomized clinical trial of the two most common uterus-sparing procedures in 26 Dutch hospitals has now been published in JAMA. The results show that a hundred-year-old method shows better results after surgery than a more recently developed method. This is a relevant finding because both in the Netherlands and worldwide more women undergo the more recent method. There is also a group of patients who benefit more from the newer procedure.
