Introduction:

The total installed base of Internet of Things (IoT)-connected devices, such as sensors in wireless sensor networks (WSN), is projected to amount to 75.44 billion worldwide by 2025, a five-fold increase in ten years. This transition will present a formidable challenge as wireless networks are hitting their physical capacity limits. Therefore, it is of utmost importance to develop radically new solutions to support this ever-increasing number of connected devices.

Intelligent reflecting surfaces (IRS) can be incorporated with environmental objects and can perform operations such as reflect, refract, absorb, polarization adjust, and modulate data onto the received signals in order to guarantee high accuracy, long-range, and large-scale wireless sensing. Recent advances in the development of artificial materials with specific electromagnetic properties have demonstrated that this breakthrough idea can become a scientific reality.

This Special Issue welcomes both reviews and original research articles in the field of wireless sensing through IRS, following the submission guidelines of Sensors, within the remit of this Special Issue call. Topics include but are not limited to planar/flexible/wearable IRS for wireless sensing with applications in agriculture, smart homes/vehicles/drones, and medical diagnostics. Microwave imaging techniques using IRS are also of interest. We invite and encourage your participation to this Special Issue.
