 wearable biosensors have been receiving increasing attention due to their unique properties such as self-powered, lightweight, low-cost, high-flexibility, detection condensants, and great conformability. These sensors can be used to detect biological fluids such as blood, urine, saliva, and sweat, and they can be fabricated using micro nanofabrication techniques. Furthermore, they can be applied in various fields, including healthcare, sports, military, and environmental monitoring. In addition, the paper discusses the latest advances in wearable biosensor technology, including pressure sensors, sweat sensors, and self-powered biosensors. The paper concludes with a discussion of the challenges and future directions of this research area. This article was authored by Jimin Song, Shuzhou, Yen Cha-chin, and others.
