• Integrated CNCs as an active electrolyte layer with printed organic semiconducting channels.
• Employed ionic-strength controlled tunable photonic band gap for signal generation.

Main Results:

• Achieved distinguishable and quantized 13-bit electric signals triggered by changes in humidity, voltage, and light polarization.
• Demonstrated integrated circuits responding to circularly polarized light and humidity as physically unclonable functional devices.
• Showcased high-level multi-valued logic capabilities.

Conclusions:

• Convergence of functional nanomaterials and multi-valued logic thin-film electronics enables novel optoelectronic applications.
• Developed a new platform for optoelectronic counterfeiting, imaging, and information processing with multilevel logic nodes.
• Paved the way for next-generation secure encryption and logic systems.
