abstract = "This article presents a focused review of past performance, recent advancements and emerging trends in liquid crystal-based reconfigurable millimeter-wave components and systems, with applications extending to the Internet of Things (IoT) and beyond. Two primary developmental trajectories are highlighted: the use of phasereconfigurable delay lines in passively fed phased-array antennas and reconfigurable intelligent surfaces (RIS) to enable adaptive communication, and the implementation of passive tunable filtering for dynamic spectrum allocation. These trends underscore an ongoing shift towards adaptable, intelligent, and energy-efficient hardware solutions, facilitating the next generation of smart, interconnected devices for IoT and AIoT (artificial intelligence of things). Furthermore, the potential of liquid crystal-based multi-modal sensing and communication is proposed and investigated, with a focus on improving power efficiency and enhancing security to support the development of future IoT ecosystems.",
