Laser‐Induced Graphene‐Based Sensors in Health Monitoring: Progress, Sensing Mechanisms, and Applications.

The rising global population and improved living standards have led to an alarming increase in non‐communicable diseases, notably cardiovascular and chronic respiratory diseases, posing a severe threat to human health. Wearable sensing devices, utilizing micro‐sensing technology for real‐time monitoring, have emerged as promising tools for disease prevention. Among various sensing platforms, graphene‐based sensors have shown exceptional performance in the field of micro‐sensing. Laser‐induced graphene (LIG) technology, a cost‐effective and facile method for graphene preparation, has gained particular attention. By converting polymer films directly into patterned graphene materials at ambient temperature and pressure, LIG offers a convenient and environmentally friendly alternative to traditional methods, opening up innovative possibilities for electronic device fabrication. Integrating LIG‐based sensors into health monitoring systems holds the potential to revolutionize health management. To commemorate the tenth anniversary of the discovery of LIG, this work provides a comprehensive overview of LIG's evolution and the progress of LIG‐based sensors. Delving into the diverse sensing mechanisms of LIG‐based sensors, recent research advances in the domain of health monitoring are explored. Furthermore, the opportunities and challenges associated with LIG‐based sensors in health monitoring are briefly discussed. [ABSTRACT FROM AUTHOR]
