Stretchable‐Fiber‐Confined Wetting Conductive Liquids as Wearable Human Health Monitors

Abstract

Wetting behaviors on stretchable supports are very common in our daily lives, however, received limited attention even they show promising potentials in flexible electronics and other fields. In this study, stretchable wetting behaviors of conductive liquids deposited onto two horizontal rubber fibers are investigated. A firm liquid/solid interaction during the stretching process can contribute to a stable liquid bridge between the fibers even under extremely stretching, showing their proof‐to‐principle ability to monitor human movement toward early diagnosis of Parkinson's disease or sports injury prevention.
