• A biomimetic serpentine dual-mode temperature-humidity sensing module was integrated.
• A low-power electro-/photothermal conversion module was coupled for thermal regulation.

Main Results:

• The system demonstrated sensitive temperature-humidity monitoring.
• Achieved low-power electrothermal (51.79°C at 1.5V) and photothermal (56.38°C at 45.51 mW cm⁻²) regulation.
• Exhibited excellent EMI shielding (1600 dB mm⁻¹ at 35 μm thickness).

Conclusions:

• The hierarchical modular design optimizes material performance and functional synergy.
• This scalable approach facilitates multifunctional integration for next-generation wearable electronics.
• The developed film offers a practical solution for advanced wearable thermal management and signal integrity.
