In traditional low-frequency energy harvesting circuits, a large matched inductor with a large size is unavoidable. To reduce the size of the circuit, this paper proposes a compact self-powered inductor-less high-efficiency piezoelectric energy harvesting circuit using a low-power-consumption gyrator. A self-powered floating gyrator inductor (FGI) is used in place of an inductor in the proposed circuit, and the required phasor response is acquired by using its voltage-current (V-I) relationship. The proposed circuit offers easy adjustability and performance benefits in small integrated circuits (IC) packages. The proposed circuit can be cost-effective and provide reduced area advantages in autonomous self-powered Internet-of-Things (IoT) and wireless sensor nodes (WSN) applications. Regarding harvested energy, the proposed circuit with a storage capacitor of 0.24F can obtain 320% improved performance than standard energy harvesting (SEH) along with the lowest power consumption of 0.25µW in self-powered operation. The proposed technique can also be applied to similar piezoelectric energy harvesting strategies with large inductors.

“…A technique of impedance matching was proposed to improve the power efficiency of the harvesting process. A well-known principle of maximum power transfer from source to a load through impedance matching of both source and load was proposed in Jackson (1959), Kim et al (2007), Brufau-Penella and Puig-Vidal (2009), Liang and Liao (2010), Kong et al (2010), Saggini et al (2010) and Pandey et al (2017). The multilayer piezoelectric size effect and DC-DC converter are used for impedance matching (Kim et al , 2007).…”

Purpose The purpose of this research paper is to explore the possibility to enhance the power transfer from piezoelectric energy harvester (PEH) source to the load. As the proposed gyrator-induced voltage flip technique (GIVFT) does not require bulky components such as physical inductors, it is easily realizable in small integrated circuits (IC) package thereby offering performance benefits, reducing area overhead and providing cost benefits for constrained self-powered autonomous Internet-of-Things (IoT) applications. Design/methodology/approach This paper presents an inductorless interface circuit for PEH. The proposed technique is called GIVFT and is demonstrated using active elements. The authors use gyrator to induce voltage flip at the output side of PEH to enhance the charge extraction from PEH. The proposed technique uses the current-voltage (I-V) relationship of gyrator to get appropriate phasor response necessary to induce the voltage flip at the output of PEH to gain power transfer enhancement at the load. Findings The experimental results show the efficacy of the GIVFT realization for enhanced power extraction. The authors have compared their proposed design with popular earlier reported interface circuits. Experimentally measured performance improvement is 1.86×higher than the baseline comparison of full-wave bridge rectifier circuit. The authors demonstrated a voltage flip using GIVFT to gain power transfer improvement in piezoelectric energy harvesting. Originality/value To the best of the authors’ knowledge, pertaining to the field of PEH, this is the first reported GIVFT based on the I-V relationship of the gyrator. The proposed approach could be useful for constrained self-powered autonomous IoT applications, and it could be of importance in guiding the design of new interface circuits for PEH.

“…In common working conditions [25], a substantial reduction in battery power consumption can be achieved by reducing or eliminating standby power [26][27][28][29][30][31][32][33][34], which can directly translate into longer system lifetime, further miniaturization, and reduced maintenance intervention frequencies. Maintenance of battery-powered nodes can also be facilitated by implementing over-the-distance wireless battery charging using radio frequency (RF) wireless power transfer (WPT) [35][36][37][38][39][40]. While these solutions can help alleviate maintenance and miniaturization problems, they cannot solve them altogether.…”

Asset tracking involving accurate location and transportation data is highly suited to wireless sensor networks (WSNs) featuring battery-less nodes that can be deployed in virtually any environment and require little or no maintenance. In response to the growing demand for advanced battery-less sensor tag solutions, this article presents a system for identifying and monitoring the speeds of assets in a WSN with battery-less tags that receive all their operating energy through radio frequency (RF) wireless power transfer (WPT) architecture, and a unique measurement approach to generate time-domain speed readouts. The assessment includes performance characteristics and key features of a system on chip (SoC) purposely designed to power a node through RF WPT. The result is an innovative solution for RF to DC conversion able to address the principal difficulties associated with maximum power conversion efficiency (PCE) with sensitivity and vice versa, a strategy, and a design optimization model to indicate the number of readers required for reliable asset identification and speed measurement. Model validation is performed through specific tests. Experimental results demonstrating the viability of the proposed advanced monitoring system are provided.
