The Edwin Kan Group has two primary research focuses:
- Near-field radio frequency (RF) sensing applied to human and animal vital sign extraction.
- RFID technologies applied to RFID tag tracking, tag-less imaging, and camera-less occupant counting.
Near-field RF Sensing
Near-field RF sensing employs RF antennas placed in the near-field region of dielectric boundary motion to achieve high sensitivity and temporal resolution sensing of motion within the region. Published applications of this technology include:
- Respiratory sensing: Respiration rate, lung volume, dyspnea quantification
- Cardiac sensing: Heart rate, Heart sounds, Ventricular/Valvular motion
We employ passive and active RFID tags to enable new sensing capabilities including:
- Precise RFID tag tracking
- Tag-less room imaging
- Camera-less privacy preserving occupant counting
