1. A drilling system, comprising:
a wellbore device, comprising:
a housing comprising a bore; and
a seal element composed of an elastomeric material, positioned within the housing, and configured to seal the bore; and
a bearing assembly supported within the housing and configured to enable the seal element to rotate relative to the housing; and
a wireless seal wear monitoring system, comprising:
a plurality of radio frequency identification (RFID) tags embedded within the seal element,
wherein the plurality of RFID tags is spaced at a plurality of radial positions relative to an axial axis of the seal element;
at least one RFID transceiver and RFID antenna disposed within a recess of the housing at an axial location adjacent at least one RFID tag of the plurality of RFID tags, wherein the RFID transceiver and RFID antenna are configured to communicate with the at least one RFID tag and a control system; and
the control system is configured to determine a depth of wear in the seal element based on a lost communication with the at least one RFID tag caused by damage of the at least one RFID tag.
