    • An apparatus for sensing a heart rate of a subject, including an eyewear frame and a heart rate sensing circuit. The sensing circuit includes first and second piezoelectric sensors configured to be in communication with the subject's skin and to generate first and second voltage signals in response to a periodic vibration in at least one artery of the subject, a first voltage amplifier configured to receive the first voltage signal and output a first amplified voltage signal related to the heart rate of the subject, a second voltage amplifier configured to receive the second voltage signal and output a second amplified voltage signal related to the heart rate of the subject, and a device configured to output a differential signal that is a representation of a difference between the first amplified voltage signal and the second amplified voltage signal that relates to the heart rate
