Abstract: In some examples, a fluidic conductive trace based radio-frequency identification device may include a flexible substrate layer including a channel, and a trace formed of a conductive fluid that is disposed substantially within the channel. The fluidic conductive trace based radio-frequency identification device may further include a sealing layer disposed on the flexible substrate layer and the trace to seal the conductive fluid in a liquid state within the channel.

Abstract: An electronic device includes a marker with a pattern of marks encoding product information of the electronic device. The pattern includes first marks having a first material with a first isotopic ratio of an element, and second marks having a second material with a second isotopic ratio of the element different than the first isotopic ratio.
