Non-invasive vital sign monitoring has become increasingly significant, offering enhanced patient comfort and enabling remote healthcare applications. This paper presents a novel, contactless system that leverages Ultra-Wideband (UWB) radar technology to continuously monitor critical vital signs, including heart rate and respiration, without physical contact. Using a radar module and an high frequency microcontroller, this system offers a wireless, non-invasive monitoring solution designed for use in both hospital and home environments. The UWB radar’s advanced capabilities allow accurate detection of subtle movements associated with heartbeats and breathing from distances up to 5 meters. This makes the system an ideal option for vulnerable patients who may find traditional monitoring methods uncomfortable or unsuitable, such as individuals with burns, infants, elderly patients, or those with contagious diseases. The absence of electrodes, wires, and sensors enhances patient comfort and mobility, reducing the likelihood of skin irritation or infection. Moreover, UWB radar technology addresses key challenges of conventional, contact-based monitoring by offering high precision and reliability while maintaining low power consumption. This innovative system thus combines accuracy and efficiency, ensuring that healthcare providers have a versatile and effective tool for monitoring vital signs continuously and remotely. It aligns with the growing need for remote health solutions, supporting safe and comfortable monitoring both in medical facilities and home care environments.
