Abstract
An agent activated non-metal antenna for an ultra-high frequency (UHF) wireless sensor having a radio frequency identification (RFID) tag in electronic communication with the non-metal antenna, and a wireless data communication integrated circuit (IC), includes a conductive stimuli-responsive hydrogel material configured to be inactive prior to an interaction with an activating agent and active upon the interaction with the activating agent. The antenna is further configured to transmit power to turn on the wireless data communication IC only when the non-metal antenna is active upon interaction with the activating agent.
