How can we live longer? The eternal question, and one that scientists have long been trying to answer.

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.

Kruti Naik, a Ph.D. candidate in ocular drug delivery at the Wits Advanced Drug Delivery Platform (WADDP) at Wits University, could change the way eye infections and conditions are treated.
