| Porous composite foam, as a novel functional material, possesses advantages such as high surface area, high porosity, low density, flexibility, and good biocompatibility. It has broad application prospects in the field of biosensors, including health monitoring, electronic skin, and biometric recognition. Firstly, this paper introduces the characteristics of porous composite foam and its construction methods such as chemical foaming, template synthesis, and self-assembly. Structural adjustments and functional modifications of the composite foam are achieved by introducing nanoparticles, biomolecules, or functional polymers to enable high-sensitivity and high-selectivity detection of external forces or biomolecules. Subsequently, the sensing mechanisms of pressure-based sensors, capacitive sensors, friction-based sensors, and biosensors based on porous composite foam are analyzed. The research progress of biosensors utilizing porous composite foam as the active layer in applications such as wearable devices, motion monitoring, and biometric recognition is discussed. Finally, the advantages and disadvantages of porous composite foam materials in the field of biosensing are summarized, and the development trends are outlined. Therefore, the construction and research progress of porous composite foam provide a theoretical basis for the further development of biosensors. |
