  • Perturbation-injection-locked physiological signal sensor
    Patent number: 11439355
    Abstract: A physiological signal sensor, comprising a self-oscillating complementary split-ring resonator (SO-CSRR), a demodulator and a microcontroller (MCU). The SO-CSRR detects a physiological signal and outputs a modulated signal, the demodulator receives the modulated signal and outputs a pulse physiological signal, the baseband amplifier receives the pulse physiological signal and outputs an amplified pulse physiological signal, and the MCU receives the amplified pulse physiological signal and outputs a digital signal.
