چکیده
This article presents a high-performance lead-free piezoelectric energy harvester (LPEH) system for magnetic field. It based on Ba0.85Ca0.15Ti0.90Zr0.10O3 + CuO 0.3 wt% (BCTZC0.3) composite was fabricated by sintering at 1450 °C. The BCTZC0.3 composite, which has an enhanced high conversion constant (d33×g33), shows improved power-generation performance when compared with conventional harvesters. BCTZC0.3-based LPEH produces instantaneous maximum power of 8.2 mW and density 107.9 mW/cm3 in weak field 250 μT. can be used to charge capacitor operate wireless sensor network (WSN) provide temperature sensing radio-frequency (RF) transmission μT proposed is promising green-energy device potentially self-powering WSN systems applied.

High Performance Lead-free Piezoelectric Material
Lead has recently been expelled from many commercial applications and materials (for example, from solder, glass and pottery glaze) owing to concerns regarding its toxicity. Lead zirconium titanate (PZT) ceramics are highperformance piezoelectric materials, which are widely used in sensors, actuators and other electronic devices; they contain more than 60 weight per cent lead. Although there ha...
متن کاملEfficiency of energy conversion for a piezoelectric power harvesting system
This paper studies the energy conversion efficiency for a rectified piezoelectric power harvester. An analytical model is proposed, and an expression of efficiency is derived under steady-state operation. In addition, the relationship among the conversion efficiency, electrically induced damping and ac–dc power output is established explicitly. It is shown that the optimization criteria are dif...

The piezoelectric material selection and the circuit design in vibrational energy harvesting are discussed. The performances of the energy-harvesting unimorph devices that captured frequencies of 60 Hz by using piezoelectric PZT-based and BT-based ceramics were evaluated. Output voltages and power from the devices depend on the amplitude and the frequency of the oscillations, and depend on the ...

متن کاملA periodic folded piezoelectric beam for efficient vibration energy harvesting
Periodic piezoelectric beams have been used for broadband vibration energy harvesting in recent years. In this paper, a periodic folded piezoelectric beam (PFPB) is introduced. The PFPB has special features that distinguish it from other periodic piezoelectric beams. The Adomian decomposition method (ADM) is used to calculate the first two band gaps andtwelve natural frequencies of the PF...
