Summary: Researchers have developed highly robust and sensitive flexible strain sensors by customizing crack-like patterns and ingeniously modulating low/high-resistance regions on a serpentine meander structure. These sensors demonstrate high cyclic stability, strong tolerance to harsh environments, high gauge factor (>1000) comparable to crack-based sensors, and fast response time (<58 ms). Integrated into a wearable sign language translation system, the sensors enable over 98% recognition rates for the translation of 21 sign languages with the assistance of machine learning. This system facilitates barrier-free communication between signers and nonsigners and has broad application prospects in gesture interaction.
