A Three-Port Zero-Power RFID Wireless Sensor for IoT ApplicationsThis paper proposes a novel battery-less wireless sensor architecture. The sensor architecture is fully passive which integrates a UHF RFID with a capacitance-based sensor. The sensor passively varies the phase of the backscattered RFID signal based on the sensed value. The phase alteration is easily determined at the receiver using a non-coherent IQ demodulation technique. The passive nature of this sensor keeps the read range of a regular UHF RFID tag unaffected, making it ideal for home and industrial applications.

Characterization of a Resonant Capacitively Coupled Wireless Power Transfer System for Communication Purposes at 6 MHzThis work characterizes a wireless power transmission (WPT) system operating at the 6 MHz frequency band for wireless information transfer purposes. To perform the characterization, the channel is modelled using its 2‐port network scattering parameters. Then, a long string of symbols encoded with on–off keying and modified Miller encoding is passed through the channel model at various data rates. The original data is recovered from the channel output signal using a software‐defined receiver. Bit error rate curves and eye diagrams are created for each encoding scheme and data rate. To verify the simulated results, the aforementioned data strings are transferred through the actual WPT system and output signals are post‐processed in the digital domain with the same software‐defined receiver. For comparison purposes, the performance of the WPT channel is compared to that of a conventional wireless communication channel with a flat additive white Gaussian noise model. The simulation and measurement results demonstrate that the provided WPT system can be used for data transfer with an acceptable error rate.T07-P06NP | Publication | 2021-02-05 | S Belau, Fabiano Domingos, Susanna Vital de Campos de Freitas, Rashid Mirzavand, Pedram Mousavi |
Low Ripple Envelope Detection for Load Modulated Communication in SWIPTIn this work we propose a new design methodology for envelope detectors in amplitude shift keyed communication. The method's premise is that a deliberately designed distortion can significantly improve the performance of a data receiver by reducing the bit error rate (BER). The main significance is in simultaneous wireless information and power transfer (SWIPT) applications where this envelope detector can be used to improve the recovery of messages transmitted from battery-less units employing load modulation. The key principle is the reduction of ripple voltage, which allows a battery-less unit to use a smaller modulation depth and thus remain in an impedance matched condition while receiving power and transmitting data simultaneously. A design criterion was developed to enable this improvement and implemented in a software-defined receiver (SDR). Data was transmitted through a wireless power transfer system designed for Qi purposes and recovered using the SDR, from which BER plots were produced and it was shown that the design indeed maximizes the performance.

Abstract: A wireless sensor is provided for use in near-to-zero or zero-power consumption applications. The sensor includes a sensing circuit, a modulator connected to the sensing circuit and configured to modulate an input signal using variations in input impedance produced by the sensing circuit to produce a modulated output signal, and a transmitting element such as an antenna to transmit the modulated output signal to a receiver. In some implementations, the sensor includes a pilot sequence generator that may be powered by a received signal from a transmitting node. The input signal is thus modulated by both pilot data and the input impedance. The input signal may be received from the transmitting node. Alternatively, a power source may be provided in the wireless sensor for generating the input signal and/or pilot data.T07-P06NP | IP Management | 2022-02-01 | Rashid Mirzavand, "Mahdi Honari", Pedram Mousavi |

ELECTROMECHANICAL RECONFIGURABLE INTELLIGENT SURFACE FOR ENHANCED WIRELESS COMMUNICATIONThe growing interest in reconfigurable intelligent surfaces (RIS) for wireless communications is evident, particularly in addressing challenges beyond the normal incidence condition of electromagnetic waves. This paper introduces an innovative approach to achieve beam steering in reflectingtype array structures, specifically reflectarrays, through the use of Reconfigurable Electro-Mechanical Reflectarray (REMR) technology. The REMR structure, equipped with a cam-shaped actuator beneath each unit cell's ground plane, serves as the basis for this design. The proposed design involves multiple reflective strips at variable elevations, enabling significant adaptability to incident waves at various angles. By incorporating a cam-shaped actuator beneath the ground plane of each unit cell, a mechanical phase shifter acts as a continuous modifier of phase for incident waves, resulting in the realization of the REMR effect. The REMR structure demonstrates consistent phase and amplitude responses, facilitating efficient beam steering. Additionally, the REMR structure maintains stability even when powered off in the "defined gradient mode" due to a memory function preserving gradient states. The fabrication process utilizes 3D printers, offering flexibility and ease of customization. This comprehensive approach holds significant potential for advancing RIS technologies.T07-P06NP | IP Management | 2024-02-22 | Rashid Mirzavand, Behrokh Beiranvand |
