Deep Learning for Radio-based Human Sensing: Recent Advances and Future Directions
Isura Nirmal, Abdelwahed Khamis, Mahbub Hassan +2
While decade-long research has clearly demonstrated the vast potential of radio frequency (RF) for many human sensing tasks, scaling this technology to large scenarios remained pro…
Simultaneous Energy Harvesting and Gait Recognition using Piezoelectric Energy Harvester
Dong Ma, Guohao Lan, Weitao Xu +2
Piezoelectric energy harvester, which generates electricity from stress or vibrations, is gaining increasing attention as a viable solution to extend battery life in wearables. Rec…
Nephalai: Towards LPWAN C-RAN with Physical Layer Compression
Jun Liu, Weitao Xu, Sanjay Jha +1
We propose Nephalai, a Compressive Sensing-based Cloud Radio Access Network (C-RAN), to reduce the uplink bit rate of the physical layer (PHY) between the gateways and the cloud se…
A Novel Emergency Light Based Smart Building Solution: Design, Implementation and Use Cases
Weitao Xu, Jin Zhang, Jun Young Kim +5
Deployment of Internet of Things (IoT) in smart buildings has received considerable interest from both the academic community and commercial sectors. Unfortunately, widespread adop…
A Survey of COVID-19 Contact Tracing Apps
Nadeem Ahmed, Regio A. Michelin, Wanli Xue +7
The recent outbreak of COVID-19 has taken the world by surprise, forcing lockdowns and straining public health care systems. COVID-19 is known to be a highly infectious virus, and…
Skin-MIMO: Vibration-based MIMO Communication over Human Skin
Dong Ma, Yuezhong Wu, Ming Ding +2
We explore the feasibility of Multiple-Input-Multiple-Output (MIMO) communication through vibrations over human skin. Using off-the-shelf motors and piezo transducers as vibration…
