Development and Piezoelectric Properties of a Stack Units-Based Piezoelectric Device for Roadway Application

Abstract: To improve the energy harvesting efficiency of the piezoelectric device, a stack units-based structure was developed and verified. Factors such as stress distribution, load resistance, loads, and loading times influencing the piezoelectric properties were investigated using theoretical analysis and experimental tests. The results show that the unit number has a negative relationship with the generated energy and the stress distribution has no influence on the power generation of the piezoelectric unit array.

“…Recent research has progressed to in situ measurements. On-site installation and evaluative experiments were carried out by embedding PEHs in roadways (Chen et al, 2021; Hong et al, 2022; Li et al, 2021; Wang et al, 2021) using suitable packing methods (Wang et al, 2019; Zhang et al, 2019), and the harvested energy was proved to be enough to power electronics include temperature sensors and wireless data transmission devices (Hwang et al, 2019).…”

“…Based on the positive piezoelectric effect of piezoelectric materials [9,10], piezoelectric energy harvesters (PEHs) can convert this kinetic energy into electrical energy (5). The developed PEHs can be utilized to power low-power sensors for traffic flow monitoring [11], structural health monitoring [8], and vehicle weight estimation [12], as well as to power electronics, such as signals, lights, and Internet of things systems [13,14]. Furthermore, research indicates that PEH technology has technical advantages, such as a low environmental impact, high energy density, and around-the-clock service, and could be the leading technology in green and intelligent roads [15].…”

“…Wang constructed simulation systems to test the electricity-generating performance of small piezoelectric stack units [24]. Li used an MTS and a wheel rutting tester to investigate the structural strength and electrical performance of a piezoelectric unit [11,21]. However, no unified testing and evaluation methods have been summarized for the mechanical and electrical performance.…”

“…Ayrıca hasat edilen enerjinin depolanması ve ihtiyaç anında kullanılabilecek olması da piezoelektrik enerji hasadına ilgiyi arttırmıştır. Li ve arkadaşları [3] karayoluna yerleştirilen ve üzerinden araç geçen piezoelektrik cihazın, gerçek bir lastik yükü altında 190 V'luk bir açık devre voltajı ile yeni piezoelektrik özelliklere sahip olduğunu ve trafik parametrelerinin voltaj dalga biçiminden çıkarılabileceğini doğrulamıştır. Cho ve arkadaşları [4] gerçek karayolu üzerine kurulu yola uyumlu bir piezoelektrik enerji toplayıcıyı üzerinde çalışmışlardır.…”
