Proposed SRO integrated MTM LWA for multi-target vital sign detection
It is essential to keep track of one’s respiration rate (RR) and heart rate (HR) for a healthier life. Existing real-time cardiovascular disease monitoring methods are mostly based on wearable solutions, such as finger pulse meters, smart watches, electrocardiograms, However, these wearables require a direct contact with the patient and can only obtain one single vital sign information at a time, besides, it may cause discomfort, skin damage, and hygiene issues. Certain radar sensing techniques, such as multiple-input multiple-output (MIMO) allow multi-target, non-contact mode vital sign monitoring. However, these techniques increase the cost of testing and have complex control schemes which limits their use.
Rutgers researchers have developed a non-contact sensor based on Doppler radar sensor for multi- target vital sign such as heart rate and respiration rate. The sensor utilizes metamaterial leaky wave antenna (MTM-LWA) integrated with a super-regenerative oscillator (SRO) architecture. Furthermore, compared with MTM-LWA radar sensor based on the self-injection-locked (SIL) architecture, vibrating motion at a farther distance can be detected accurately using the proposed radar sensor, indicating a higher sensitivity with reduced system complexity.
