摘要

This paper presents a microwave perturbation-injection-locked (PIL) sensor with the self-oscillating complementary split-ring resonator (SO-CSRR) for the wrist pulse detection. The output of the SO-CSRR is then connected with the amplitude-based demodulator, which is composed of a microwave differentiator and an envelope detector, to acquire the wrist pulse. Since the SO-CSRR can generate and concentrate the electric field in the near-field region, it significantly increase the sensor sensitivity. The measured wrist pulse rate and waveform shape of the proposed PIL sensor agree those acquired by photoplethysmograph (PPG) sensor very well.
