Joseph Walish - Cambridge MA, US
Edwin L. Thomas - Natick MA, US

Assignee:

Massachusetts Institute of Technology - Cambridge MA

International Classification:

G01J 3/46
G02F 1/03

US Classification:

356402, 359321

Abstract:

The present invention provides polymeric materials arranged as photonic crystals, or portions of photonic crystals, having properties which can be easily tuned over a large range of wavelengths upon exposure to an external stimulus. In some embodiments, the photonic crystals comprise at least one portion which can undergo a change in a physical, chemical, dielectric, or other property upon exposure to an altering stimulus, resulting in a change in a diffracted wavelength of electromagnetic radiation (e.g, light) by the photonic crystal. Embodiments of the invention may advantageously exhibit large stop band tunability and rapid response times. Photonic crystals of the invention may be useful in a wide variety of applications, such as colorimetric sensors, active components of simple display devices, electrically controlled tunable optically pumped laser, photonic switches, multiband filters, and the like.

G06K 7/14

Abstract:

Components, systems, and methods for detection of volatile ions and related methods are generally provided. In some embodiments, the components, systems, and methods are configured for use with mass and/or ion mobility spectrometry. In some embodiments, a characteristic of an article (e.g., identity, authenticity, property, adulteration, product associated information such as age or quality, etc.) may be determined by determining the presence (e.g., an amount) or absence of one or more ionic species emanating from the article. For example, the presence or absence of the one or more ionic species emanating from the article identifies a characteristic of the article. In some embodiments, the one or more ionic species have been proactively added to the article.

Abstract:

Components, systems, and methods for gas sensing identification are generally disclosed. In some embodiments, a characteristic of an article (e.g., identity, authenticity, property, product associated information such as age or quality, etc.) may be determined by determining the presence (e.g., an amount) or absence of a chemical compound (or compounds) emanating from the article. For example, the presence or absence of the compound (or compounds) emanating from the article identifies a characteristic of the article. In some embodiments, the chemical compound(s) has been proactively added to the article. That is to say, in some embodiments, the chemical compound is not inherently associated with the article but is added in order to, for example, identify a characteristic of the article.
