In recent years, flexible sensors have gained increasing attention due to their excellent flexibility. Liquid metal (LM) has gradually become an ideal material for fabricating sensors, thanks its outstanding electrical conductivity and low-temperature fluidity. However, oxidation the need secondary activation of LM present significant technical challenges in development sensors. this paper, we introduce a simple method that integrates flexibility polydimethylsiloxane (PDMS) fabricate with sandwich structure. The sandwich-structured sensor demonstrates superior effectively prevents mechanical activation. Additionally, PDMS-LM exhibits performance under various conditions, fast response time stimuli (0.5 s), as well durability stability (>10,000 s cycling). These remarkable properties give great potential field human motion monitoring, bringing further direction intelligent sensing technology.
