Cardiovascular disease is responsible for an estimated 17.9 million deaths each year, making it the leading cause of death worldwide. Continuous heart health monitoring way is the best preventative for heart failure. However, standard monitoring devices, including ECG and PPG, require direct physical contact, which can be difficult for certain patient...

When searching for missing persons, especially during emergency situations, such as catastrophic weather and infrastructure or geologic events, aerial reconnaissance can be an invaluable tool, particularly if the area is large and/or unstable. Unmanned aerial vehicles (UAVs) with thermal imaging capabilities can help detect heat signatures from victims,...

Vital signs, such as heart and respiratory rate, provide critical insight into a person’s health. Radar has been used to remotely analyze and detect human activity and vital signs for many years. Despite all the great features such as motion sensitivity, privacy preservation, penetrability, and more, radar has limited spatial degrees of freedom...

Heart rate and other cardiac function monitoring is conventionally performed in a healthcare setting utilizing devices such as EKGs and finger pulse oximeters. While effective, this requires physical contact with the patient and a doctor visit, making continuous or long-term monitoring difficult. Microwave radars have been used extensively for...

Background Modern commercial communication systems, such as 5G networks, commonly operate at relatively high radio frequencies toward the millimeter wave bands. In conventional satellite communication systems, large reflectors or dishes are required for high-speed communication, which suffer from high mechanical complexity, high operation and maintenance...
