    Abstract: A representative printable composition comprises a liquid or gel suspension of a plurality of metallic particles; a plurality of semiconductor particles; and a first solvent. The pluralities of particles may also be comprised of an alloy of a metal and a semiconductor. The composition may further comprise a second solvent different from the first solvent. In a representative embodiment, the first solvent comprises a polyol or mixtures thereof, such as glycerin, and the second solvent comprises a carboxylic or dicarboxylic acid or mixtures thereof, such as glutaric acid. In various embodiments, the metallic particles and the semiconductor particles are nanoparticles between about 5 nm to about 1.5 microns in any dimension. A representative metallic and semiconductor particle ink can be printed and annealed to produce a conductor.

    Abstract: In one embodiment, a security label comprises a random arrangement of printed LEDs. During fabrication of the label, the LEDs are energized, and the resulting dot pattern is converted into a unique digital first code and stored in a database. The label is then attached to an object to be later authenticated, or the LEDs are printed directly on the object, such as a passport, license, bank note, certificate, etc. For authenticating the object, the LEDs are energized and the dot pattern is converted into a code. The code is compared to the first code stored in the database. If there is a match, the object is authenticated. The label may also have a printed second code associated with the first code, and both codes must match codes stored in the database for authentication. The general shape of the printed pattern may convey the proper orientation of the pattern.

    Abstract translation: 在一个实施例中，安全标签包括印刷的LED的随机排列。 在制造标签期间，LED被激励，并且所得到的点图案被转换成唯一的数字第一代码并存储在数据库中。 然后将标签附着到待认证的对象上，或者将LED直接打印在对象上，例如护照，许可证，纸币，证书等。为了认证对象，LED被激活，点图案 被转换成代码。 将代码与存储在数据库中的第一个代码进行比较。 如果有匹配，则对象进行身份验证。 标签还可以具有与第一代码相关联的打印的第二代码，并且两个代码必须匹配存储在数据库中的代码以进行认证。 印刷图案的一般形状可以传达图案的正确取向。
