Abstract

This article presents a high-performance lead-free piezoelectric energy harvester (LPEH) system for magnetic field. It based on a Ba 0.85 Ca 0.15 Ti 0.90 Zr 0.10 O 3 + CuO 0.3 wt% (BCTZC 0.3 ) composite was fabricated by sintering at 1450 °C. The BCTZC 0.3 composite, which has an enhanced high energy conversion constant ( d 33 × g 33 ), shows improved piezoelectric power-generation performance when compared with conventional piezoelectric energy harvesters. The BCTZC 0.3 -based LPEH produces instantaneous maximum power of 8.2 mW and an energy density of 107.9 mW/cm 3 in a weak magnetic field of 250 μT. This system can be used to charge a capacitor and operate a wireless sensor network (WSN) system to provide temperature sensing and radio-frequency (RF) transmission in a 250 μT magnetic field. The proposed LPEH is a promising green-energy device for potentially self-powering WSN systems when applied.
