As an application of fine-grained wireless sensing, RF-based material identification follows
the paradigm of RF computing that fetches the information during RF signal propagation …

This paper introduces RFVibe, a system that enables contactless material and object
identification through the fusion of millimeter wave wireless signals with acoustic signals. In …

WiFi has gradually developed into one of the main candidate technologies for ubiquitous
sensing. Based on commercial off-the-shelf (COTS) WiFi devices, this paper proposes …

With the advancement of wireless sensing technologies, RF-based contact-less liquid
detection attracts more and more attention. Compared with other RF devices, the mmWave …

Human external biofluid (eg, sweat, urine) contains vast health data that is readily
harvestable. Currently, wearable sweat sensors require an electrochemical-based approach …

The existing RF-based liquid identification systems usually rely on prior knowledge, such as
pre-build database or the material and width information of the vessel. Furthermore, existing …

Wireless sensing offers a promising approach to identify the content of liquids without
opening the container or directly touching the liquid. Although existing methods aim to …

People increasingly carry wearables and the capabilities of these devices have reached a
point where it is increasingly possible to harness the devices to support everyday …
