“…The second PZT-based piezoelectric EH (EH2) shown in Figure 3 a for further system testing is more advanced and fabricated using screen-printing technology on a stainless steel (SS) substrate. The design employs a so-called meandering geometry which is centrally-supported [ 28 ]. This structure is known to be capable of achieving better power efficiency than that of a zigzag structure owing to the reduced torsional mode effects in the clamped beam [ 29 ].…”

Real time electricity monitoring is critical to enable intelligent and customized energy management for users in residential, educational, and commercial buildings. This paper presents the design, integration, and testing of a simple, self-contained, low-power, non-invasive system at low cost applicable for such purpose. The system is powered by piezoelectric energy harvesters (EHs) based on PZT and includes a microcontroller unit (MCU) and a central hub. Real-time information regarding the electricity consumption is measured and communicated by the system, which ultimately offers a dependable and promising solution as a wireless sensor node. The dynamic power management ensures the system to work with different types of PZT EHs at a wide range of input power. Thus, the system is robust against fluctuation of the current in the electricity grid and requires minimum adjustment if EH unit requires exchange or upgrade. Experimental results demonstrate that this unit is in a position to read and transmit 60 Hz alternating current (AC) sensor signals with a high accuracy no less than 91.4%. The system is able to achieve an operation duty cycle from <1 min up to 18 min when the current in an electric wire varies from 7.6 A to 30 A, depending on the characteristics of different EHs and intensity of current being monitored.

“…The specific design parameters of this energy harvester are provided in Table 2.1 [9]. The circuitry developed here will be ultimately integrated with a more advanced PZT EH that is developed and reported by our research team [6]. Compared to the simple cantilever structure of similar area, the newly developed design has the required fundamental natural frequency of 60 Hz and maintains a high power output.…”

“…Compared to the simple cantilever structure of similar area, the newly developed design has the required fundamental natural frequency of 60 Hz and maintains a high power output. This centrally supported meandering geometry (presented in Figure 2.4 [11]) uses the symmetry around a clamped beam to mirror two zigzag structures which further reduce the overall design area. simplified model is sufficient for the design of the interface circuitry and will be used in this work.…”

“…An electromagnetic EH fabricated by the Energy Harvesting team at the University of Waterloo was used as a prototype for the design of the interface circuitry as well as the control and communication systems. We will be integrating the circuitry developed here with the meandering PZT EH that is under development by the University of Waterloo research team and has been reported in literature [6]. However, a brief and preliminary review of EHs will be done in the following section to provide readers with the necessary information regarding the operation of EHs and their electromechanical characteristics.…”

Growing interest in improving the energy consumption efficiency in residential and commercial buildings has led to the emergence of intelligent energy management systems. This growing technology allows the transformation of the outdated electric distribution network within buildings to a smart and intelligent system. A major challenge in the development of such infrastructure is the need for low cost, integrated, self-contained, and non-invasive wireless sensor nodes. While an electric meter provides the utility company with information regarding the total energy consumption, no information is provided to the consumers regarding the energy consumed by individual appliances. Such visibility can provide consumers with the ability to better control and manage their energy usage leading to a reduced overall energy consumption.This work explores the design and development of a self-contained and non-invasive integrated system intended for real-time electricity monitoring within residential and commercial buildings. The proposed system includes an Energy Harvester, an electric current sensor, a Micro-controller Unit, and a wireless communication device. The proposed system is self-powered and non-invasive, which offers a promising solution in providing real time information regarding the energy distribution within buildings.The design featured in this work provides an innovative approach in the development of a customized interface circuitry that is designed to collect and regulate the energy from the Energy Harvester.The entire sensor node will operate under a power budget in the range of microwatts collected by the Energy
