Research interests: RF/microwave/mm-wave circuits and systems, integration of mm-wave systems, short-range radar sensing and its applications in human-computer interaction, Internet of Things, medical and healthcare.

人机交互 Touchless Human-Computer Interaction

Human hands are natural tools for performing actions and gestures that interact with the physical world. Radar technology allows for touchless wireless gesture sensing by transmitting radio frequency (RF) signals to the target, analyzing the backscattering reflections to extract the target’s movements, and thereby accurately detecting gestures for Human Computer Interaction (HCI). A key advantage of this technology is that it allows interaction with machines without any need to attach a sensing device to the hands.

医疗健康监测 Noncontact Health Monitoring

Many patients have the uncomfortable experiences of lying on bed, monitored by all kinds of wired medical instruments. What if a person’s vital signs can be monitored when he or she just lays or sits down or even is cooking in the kitchen, without all these messy wires? No sensor is needed to be attached to the body that may cause skin effect and nervousness to affect the response. Most importantly, it'll be no longer necessary for the subject under monitoring to stay still, which makes the monitoring process much more flexible and comfortable. This dream is becoming true with the development of our noncontact health monitoring technologies.
