1. A wearable device comprising:
a biometric circuit configured to monitor one or more biometrics of a user wearing the wearable device;
a first conductive element;
a first decoupling element configured to selectively couple the first conductive element to the biometric circuit such that the first conductive element operates as an electrode for the biometric circuit;
a second decoupling element configured to selectively couple the first conductive element to an electrical ground such that the first conductive element operates as an antenna; and
a first antenna matching circuit coupled between the second decoupling element and the electrical ground.
