Conventional wearable sweat sensors utilize hydrophobic ion-selective membranes (ISMs) and require tight contact and adhesives to achieve signal stability. However, this can lead to user discomfort and skin-related diseases, necessitating the development of non-contact alternatives. In a new study, inspired by the self-cleaning behavior of rose petals, researchers developed novel ISM-based sweat sensors that feature enhanced signal stability and performance, avoid skin contact, and are reusable, making them practical for daily use.
Wearable sensors can help prevent critical health issues by continuously monitoring physiological factors in real time. Specifically, sweat monitoring can provide valuable insights into electrolyte balance and overall health. Sodium concentration in sweat is a key indicator of hydration and muscle performance. Thin film materials, such as carbon...
