Wi-Fi localization and tracking face accuracy limitations dictated by antenna count (for angle-
of-arrival methods) and frequency bandwidth (for time-of-arrival methods). This paper …

Target imaging and material identification play an important role in many real-life
applications. This paper introduces TagScan, a system that can identify the material type …

Kinetic energy harvesting (KEH) may help combat battery issues in wearable devices. While
the primary objective of KEH is to generate energy from human activities, the harvested …

Even though indoor smoking ban is being put into practice in civilized countries, existing
vision or sensor-based smoking detection methods cannot provide ubiquitous smoking …

In this paper, we design and develop RIO, a novel battery-free touch sensing user interface
(UI) primitive for future IoT and smart spaces. RIO enables UIs to be constructed using off-the …

Many object localization applications need the relative locations of a set of objects as
oppose to their absolute locations. Although many schemes for object localization using …

Backscatter is an enabling technology for battery-free sensing in today's Artificial Intelligence
of Things (AIOT). Building a backscatter-based sensing system, however, is a daunting task …

This paper studies the problem of tag localization using RFID-augmented robots, which is
practically important for promising warehousing applications, eg, automatic item fetching …

Increasing numbers of everyday objects in libraries, stores and warehouses are
instrumented with passive RFID tags, resulting in a ripe opportunity for gesture-based …

Passive Radio Frequency IDentification (RFID) tags are commonly used to provide Radio
Frequency (RF) accessible unique identifiers for physical objects due to their low-cost, lack …
