Chronic wounds pose a significant challenge to healthcare professionals, not only due to their prolonged healing times but also because severe cases can lead to amputations and life-threatening risks for patients. However, existing wound monitoring sensors typically monitor only a single parameter of wound status and often experience crosstalk when detecting multiple types of information simultaneously. We propose a multifunctional wound monitoring sensor based on laser-induced graphene, which not only exhibits superior sensing performance and remarkable stability but also allows for non-interference monitoring of multiple wound-related parameters, such as pH, temperature, and strain. The sensor can detect a minimal strain of 0.3%, with linearity exceeding 99.5% for both temperature and pH detection, and retains its sensitivity after 4000 cycles under 5% strain. As a proof-of-concept demonstration, we have verified the feasibility of this sensor in sensitive areas such as the corner of the human eye, as well as in common and special chronic wound conditions. The design concept and comprehensive guidelines presented would provide insights into multifunctional sensor development, promising benefits for health monitoring.
