Wearable Doppler radar health monitor with gesture control

This paper presents wearable health monitors based on Doppler radar technology. To achieve low complexity and power consumption, the radar architecture is composed of a self-injection-locked oscillator (SILO) tag and an injection-locked oscillator (ILO) based IQ frequency demodulator. Promisingly, the experimental results as presented in this paper show that the proposed monitoring system has high potential to integrate wireless transmission device, vital-sign sensor, pedometer and gesture controller on a single radar platform.
