  In an era driven by the Internet of Things (IoT) and rapid wireless
communication advances, the synergy between sensing and backscatter
communication (BackCom) has emerged as a frontier of research. This paper
delves deep into the integration of sensing technologies with BackCom, a
burgeoning field with significant implications for energy-efficient wireless
systems. By tracing the historical developments and principles of BackCom, we
establish the foundational understanding crucial for integrating advanced
sensing methodologies. Our study adopts a mixed-method approach, combining
quantitative analyses of system performances with qualitative assessments of
various integration techniques. Furthermore, these integrated systems showcase
enhanced adaptability in dynamic environments, a pivotal attribute for future
IoT applications. These findings hold profound implications for industries
focusing on smart technologies, as they underscore the potential for achieving
both sustainable and efficient communication. Our research distinguishes itself
by not only highlighting the benefits but also addressing the challenges faced
in this integration, providing a comprehensive overview of the topic.
