Abstract
Activatable indicator platforms for integrated circuits using microencapsulation are disclosed herein. An example activatable indicator platform includes an RFID tag, including an antenna; an integrated circuit, electrically connected to the antenna; an electrical loop having an open state and a closed state, the electrical loop electrically connected to the integrated circuit; an activatable environmental exposure indicator included as a portion of the electrical loop, the indicator having a conductive state and a nonconductive state, such that the electrical loop is in the closed state when the activatable environmental exposure indicator is in the conductive state and the electrical loop is in the open state when the activatable environmental exposure indicator is in the nonconductive state.
