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.

A new generation of biosensors is transforming how we monitor health—by stretching with the body and sensing multiple signals in real time. Scientists have developed highly flexible biosensors that detect sweat pH, electrolyte levels, and electromyography (EMG) signals simultaneously. Their secret lies in a hybrid microstructure (HMS) that combines wave-like flexibility with microcrack stress dispersion, ensuring both durability and precision. Even under 60% strain or after 5000 stretching cycles, the sensors retain electrical stability. Coated with conductive polymers, the devices provide continuous and accurate feedback, making them ideal for next-level wearable technologies in personalized health monitoring.
