Humidity Sensors Mimicking Cuticle of Hercules Beetles

Abstract This paper reports a biomimetic humidity sensor inspired by the humidity-dependent color change observed in the cuticle of the Hercules beetle. A film-type humidity sensor with nanoporous structures based on 3D photonic crystals was designed and fabricated using the colloidal templating method and a surface treatment. The visible color of the fabricated humidity sensor [...]
