摘要：
One example system for enabling NFC communications with a wearable biosensor includes a biosensor applicator including a housing defining a cavity configured to receive and physically couple to a biosensor device, and to apply the biosensor device to a wearer； a first applicator coil antenna physically coupled to the housing and defined within a first plane； and a second applicator coil antenna physically coupled to the housing and defined within a second plane substantially parallel to and different from the first plane, the second applicator coil antenna positioned coaxially with respect to the first applicator coil antenna, wherein the first applicator coil antenna is configured to wirelessly receive electromagnetic (“EM”) energy from a transmitter coil antenna of a remote device and provide at least a first portion of the received EM energy to the second coil antenna； and a biosensor device including a biosensor coil antenna defined within a third plane substantially parallel to and different than the first and second planes； a wireless receiver electrically coupled to the biosensor coil antenna； wherein the biosensor device is physically coupled to the biosensor applicator and positioned within the cavity； wherein the biosensor coil antenna is positioned and oriented substantially coaxially with respect to the second applicator coil antenna, and wherein the second applicator coil antenna is configured to receive EM energy from the first applicator coil antenna and wirelessly transmit at least a second portion of the received EM energy to the biosensor coil antenna.
