We design and prototype the first battery-free video streaming camera that harvests energy
from both ambient light and RF signals. The RF signals are emitted by a nearby access …

Realizing the vision of ubiquitous battery-free sensing has proven to be challenging, mainly
due to the practical energy and range limitations of current wireless communication systems …

Occupancy detection systems are commonly equipped with high-quality cameras and a
processor with high computational power to run detection algorithms. This paper presents a …

The increasing number of embedded, plugged-in radios around homes and offices in
everyday objects such as appliances, TVs, and smart speakers provides an excellent …

Backscatter communication has been a popular choice in low-power/battery-free sensor
nodes development. However, the effect of RF source to receiver distance on the operating …

Many regions of the world benefit from heating, ventilating, and air-conditioning (HVAC)
systems to provide productive, comfortable, and healthy indoor environments, which are …

The vision of ubiquitous battery-free sensing has run into the practical limitations of wireless
communication networks. To address this, we design the first wide-area and scalable …

Wireless video streaming has recently become an exciting topic of research in IoT, computer
vision, and security systems. However, for some of these applications, power consumption of …

Backscatter communication suggests a low-cost solution to connect billions of devices
through wireless signals and realize the vision of the Internet Of Things (IoT). However, due …
