Magnetically assembled photonic crystal film for humidity sensing
Abstract
A novel Fe3O4@SiO2/PEG acrylate photonic crystal humidity sensor has been fabricated by combining magnetic assembly and photo-polymerization. The sensor self-displays brilliant colors as the humidity changes. By optimizing the cross-linking level and the thickness of the polymer film, the reflection wavelength can shift 160 nm in several minutes, while its intensity is readable by the naked eye. The tested sensors demonstrate good reversibility and durability in cycling experiments. Such photonic crystal sensors may have great potential as energy efficient devices, as no electric power is required for their operation.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
