1. Fabrication of Laser-induced Graphene Heater Integrated into Flexible Printed Circuit Boards

Flexible Printed Circuit Board (FPCB) are widely used in portable devices, wearable systems, and biomedical sensing applications because their flexibility, thinness, and high integration. With the development of the Internet of Things and smart agriculture, sensors are evolving toward lightweight and multifunctional designs, including applications in temperature and humidity monitoring, pressure sensing, physiological signal acquisition, and gas detection. Most gas sensors require high-temperature... C. Wang
