Abstract
The present disclosure provides methods, systems and devices for a photonic crystal combinatorial sensor. The photonic crystal sensor may include an array of photonic crystal materials, wherein each photonic crystal material has a reflected wavelength in a respective initial wavelength range. At least one a first one of the photonic crystal materials may be configured to have a response to an external stimulus different from at least a second one of the photonic crystal materials, the different response resulting in a change in the reflected wavelength of the first photonic crystal material that is an optically detectable difference from the second photonic crystal material. The optically detectable difference may provide an optically detectable response pattern of reflected wavelengths in the array. The sensor may be reversible and reusable.
