Summary: This article introduces a wireless passive vibration sensor based on harmonic backscattering. By connecting a commercial piezoelectric cantilever to an NMOS transistor, the amplitude modulation of the backscattered second harmonic is achieved, which allows for the detection of vibration information.

Summary: In fully-connected passive RFID backscatter networks, accurate range estimations are challenging due to complex channels. To mitigate multipath and achieve accurate ranging, a differential analysis based anti-multipath technique is proposed by introducing a reference tag. Under distributed localization schemes, a virtual-actual assembling algorithm called VIABLE is proposed to achieve distributed and cooperative localization, which rectifies the fragments repeatedly until their errors converge. Theoretical analysis of performance limit is presented through the derivation of Cramer-Rao lower bound, and extensive simulations show that the proposed framework outperforms existing algorithms for cooperative localization.

Summary: This article introduces multistate chipless RFID tags that enhance the vibration sensing range and reading robustness. The proposed tags consist of a resonant scatterer trapped between two different dielectric layers, causing the appearance of multiple modulation states during vibration. The motion-induced near-field modulation increases the modulated portion of the backscattered power, which enlarges the sensing range. The experimental results show that the M-S chipless RFID tag can successfully detect submillimeter vibrations through a wall at a 2.5-meter distance.

Summary: Tag identification is crucial in large-scale RFID applications. Current schemes divide the time frame into slots and map tags to them, but this may result in tag collisions. To overcome this issue, a Group Tag Identification (GTI) framework is proposed in this paper, which leverages tag-correlation to identify grouped tags in the collision slots without additional transmission overhead. Extensive simulations show that GTI significantly reduces identification delay compared to existing schemes.

Summary: Mobile payment has experienced explosive growth by using NFC and barcodes, with the former being more secure, user-friendly, and convenient. However, due to the lack of NFC modules or security concerns, NFC functionality is not available in almost half of current smartphones. To address this, MagCode proposes a cross-technology communication between NFC reader and camera, utilizing harmless magnetic interference to encode data and achieve communication with NFC-denied or NFC-disabled smartphones. Through extensive evaluations, MagCode demonstrates superior throughput and accomplishes data exchange within an average time of 1.8 seconds.

Summary: Estimating the angle-of-arrival (AoA) of an RF source has been a classical topic in wireless systems, but it is not yet widely used for IoT due to high cost. This work introduces a novel sparse planar array, LSAB, which can estimate the AoA of an IoT device in 3D space using a few antennas connected to a single timeshare channel. The benchmark shows that LSAB performs comparably to a uniform planar array and achieves over 40% performance improvement compared to existing sparse arrays.
