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.
