A new cuffless methodology of measuring the blood pressures (BPs) of human subjects is designed using a microwave near-field self-injection-locked (NFSIL) wrist pulse sensor. The NFSIL wrist pulse sensor is primarily composed of a self-oscillating complementary split-ring resonator and an amplitude-...
