Vital signs, such as breathing and heartbeat, are useful information for health monitoring since such signals provide important clues of medical conditions. Effective solutions are needed to provide contact-free, easy deployment, low-cost, and long-term vital sign monitoring. Exploiting wireless signals for contact-free vital sign monitoring will be an important part of the future healthcare Internet of Things (IoT). In this talk, we present our recent work on contact-free vital sign monitoring. The first part is to exploit channel state information (CSI) phase difference data to monitor breathing and heartbeat with commodity WiFi devices. We will present PhaseBeat, a discrete wavelet transform based design, and TensorBeat, a tensor decomposition based design, as well as our experimental study to validate their performance. The second part of this talk is to exploit a 20KHz ultrasound signal for breathing rate detection. We will present our smartphone App based implementation. The third part of the talk is on radio-frequency identification (RFID) based vital sign monitoring, where RFID tags are used as wearable sensors attached to the human body. We will investigate the various technical challenges on fully exploiting RFID for vital sign monitoring and human activity recognition and tracking, and then review several of our recent works on RFID based human vital sign monitoring, drowsy driving detection, and 3D human pose monitoring and tracking. Our experimental study shows that the proposed systems can achieve high accuracy under different environments for vital sign monitoring.
