This paper presents an analytical and experimental study on the effect of mechanical impact parameters on impact-mode piezoelectric ceramic power generators. The parameters are the velocity and mass. The method of analysis is based on a weight drop experiment. The results show that the peak of the instantaneous output voltage is proportional to the impact velocity, and for the output power, it is...
This paper presents a study on effect of two mechanical impact parameters on impact mode piezoelectric power generation. The parameters are velocity and mass. Free fall experiment is used as the evaluation method. It turns out that peak of instantaneous output voltage is proportional to the impact velocity and for output power it is in a straight line relationship with the same parameter. For the...
Vibration energy regeneration with lead zirconate titanate piezoelectric (PZT) device has been reported by many researchers for many years. Various factors influence the energy regeneration efficiency of the PZT devices in converting the mechanical vibration energy to the electrical energy. This paper presents the analytical and experimental evaluation of energy regeneration efficiency of PZT devices...
In achieving the practical use of vibration power generation, the challenges are that the energy to be generated is small and the vibration frequency range for efficient power generation is limited. So, it is needed to improve the output level and establish a vibration transmission structure capable of covering a wider vibration frequency range. In this report, we propose a multi-axis vibration power...
The present paper describes the development of a three-axis vibration machine that precisely reproduces the vehicle's acceleration characterized by multi-mode vibration. For reproduction along the vertical axis, a system identification experiment of the vibrator is first performed. Using the identified model, the feedforward control based on the pole-zero cancellation method is applied in order to...
Vibration power generation is one of energy harvesting technologies using renewable energy. In this paper, a novel vibration power generation device for vehicles where effective power generation can be obtained by multi-mode vibration of the vehicles is presented. First, road tests of the vehicle are performed, and then the obtained data is analyzed. Next, a vibration power generation device specially...
