Serafin is a full-stack, sub-mW, and versatile RF sensor that brings transparent RF sensing to any mobile and IoT device: it independently conducts the whole RF sensing process from RF signal reception to sensing result computation in a wide variety of sensing tasks with only negligible power consumption.
Details of Serafin can be found in the paper "Bringing Transparent RF Sensing to Any Device", which is published in the 31st Annual International Conference On Mobile Computing And Networking (MobiCom 2025).
This is a demo of Serafin.
