One limitation of commercialized wearables, such as smartwatches and bands, is that they cannot form conformable contact with human skin due to their rigid form factor, thereby limiting their monitoring capabilities. Soft bioelectronics, on the other hand, are touted as an ideal platform for personalized health care owing to unique characteristics, such as thinness, lightweight, good biocompatibility, excellent mechanical robustness, and great skin conformability. Permeable skin-mountable electronics that are capable of long-term applications have emerged as promising tools for early disease prevention, screening, diagnosis, and treatment<sup>1,2</sup>. Dr. Wang’s research interests mainly focus on the development of wearable electronics for biomedical health monitoring, including stretchable conductors, sensors, and soft energy devices. In today’s talk, she will introduce high-performance skin bioelectronics developed by ultrasoft nanomesh systems, which can realize the accurate measurement of minus skin deformations and finger touch without disturbing natural skin motions and sensations, as well as long-term applications for health monitoring<sup>3-5</sup>.<br/><br/>[1] A.
