| 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.

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 University of Alberta | Publication | 2021-02-05 | S Belau, Fabiano Domingos, Susanna Vital de Campos de Freitas, Mirzavand, R., 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 University of Alberta | IP Management | 2022-02-01 | | | Detection of soil moisture, humidity, and liquid level using CPW based interdigital capacitive sensorT07-P06NP University of Alberta | Publication | 2022-06-01 | | | A Battery-Less Non-Hybrid Six-Port RFID-Based Wireless Sensor Architecture for IoT ApplicationsT07-P06NP University of Alberta | Publication | 2023-03-20 | | | Engineering Research Chair in Intelligent Wireless Communication and Sensing, University of AlbertaDr. Mirzavand was selected as the University of Alberta Engineering Research Chair in Intelligent Wireless Communication and Sensing for a five-year term.
