Sleep monitoring plays an important role in many medical applications, including SIDS
prevention, care of patients with pressure ulcers, and assistance to patients with sleep …

Radio frequency identification (RFID) technology, which is one of the important
implementation ways of Internet-of-Things (IoT), has achieved much attention in indoor …

We present the vision of BARNET (Backscattering Activity Recognition NEtwork of Tags), a
network of passive RF tags that use RF backscatter for tag-to-tag communication. BARNET …

We characterize the performance of a backscatter tag-to-tag (T2T) multi-hop network. For
this, we developed a discrete component-based backscatter T2T transceiver and a …

The COVID-19 pandemic drastically changed our way of living. To minimize life losses, multi-
level strategies requiring collective efforts were adopted while waiting for the vaccines' …

Radio frequency (RF)-powered backscatter communication between passive tags holds
tremendous potential as an enabling technology for a ubiquitous “Internet of Things.” We …

Wireless power transfer technique aiming at wireless energy provision has emerged as a
prominent solution to the architecture of long-term and self-sustainable wireless systems …

The main obstacles to achieve truly ubiquitous sensing are (i) the limitations of battery
technology-batteries are short-lived, hazardous, bulky, and costly-and (ii) the unpredictability …

Batteryless energy-harvesting sensor nodes can operate indefinitely, but if the harvesting
rate is too low, they must operate intermittently. Intermittent operation imposes various …

We envision a future where every object in our living and working environment will carry one
or more RF tags. Based on the backscattering tag-to-tag communication link, these RF tags …
