Here’s a detailed list of wearable products that utilize the Doppler Effect for various applications:

• Vayyar Care is a non-contact health monitoring system developed by Vayyar Imaging. It uses a 60GHz mmWave RF-based Doppler radar sensor to detect fine movements such as respiration, heart rate, presence detection, and falls. By leveraging the Doppler effect, the system can detect subtle motion and accurately measure distances, making it ideal for elderly care and continuous vital sign monitoring.
• Garmin Varia Radar is a rear-view radar device for cyclists developed by Garmin. It utilizes Doppler radar technology to detect approaching vehicles from behind, measuring their relative speed and distance. This information is used to provide real-time alerts to riders, enhancing safety on the road.
• Walabot Home, developed by Walabot, is an indoor fall detection system that employs Ultra-Wideband (UWB) radar combined with the Doppler effect. It can sense motion—even through walls—and determine whether a person is moving or stationary. It is particularly designed to detect sudden movements like falls, providing an added layer of safety for elderly individuals.
