Micropower energy harvesting is one of key technologies for the micromation and practical development of wireless sensor and communication node networks. A self‐adaptive piezoelectric vibration system based on modified homogeneous strain asymmetric PZT piezoelectric ceramic cantilever beam for the micropower energy harvesting was designed and prepared. A vertical cantilever was designed at the first time to obtain the homogeneous state of stress which can largely increase the power output and energy harvesting efficiency of piezoelectric cantilevers. In order to achieve the self‐adaptive vibration, the asymmetric structure was adopted. Asymmetric cantilevers moved horizontally and changed the length of main cantilevers when affected by the variation in external frequency excitation, thus, the switching of resonant frequency was archived automatically without dissipating additional energy.

“…The output voltage of piezoelectric cantilever is proportional to the acceleration. 16,17 Figure 8B shows the output voltages at different accelerations. The peak output voltage can reach 22.2 V at 1.0 g. The lower output voltage than the simulations maybe due to the defect of manufacturing process.…”

“…In the aspect of using piezoelectric materials to collect and harvest vibration energy, various studies have been carried out in recent years. Gong Junjie and Ruan Zhilin [17] et al investigated the influence of the external excitation's frequency and amplitude on the power generation capacity of a multi-layer cantilever piezoelectric power generation device through finite element model analysis. J. Rastegar showed that the piezoelectric materials could be used in low-frequency vibration environments [18].…”

A while-drilling energy harvesting device is designed in this paper to recovery energy along with the longitudinal vibration of the drill pipes, aiming to serve as a continuous power supply for downhole instruments during the drilling procedure. Radial size of the energy harvesting device is determined through the drilling engineering field experience and geological survey reports. A piezoelectric coupling model based on the selected piezoelectric material was established via COMSOL Multiphysics numerical simulation. The forced vibration was analyzed to determine the piezoelectric patch length range and their best installation positions. Modal analysis and frequency response research indicate that the natural frequency of the piezoelectric cantilever beam increased monotonously with the increase of the piezoelectric patch’ thickness before reaching an inflection point. Moreover, the simulation results imply that the peak voltage of the harvested energy varied in a regional manner with the increase of the piezoelectric patches. When the thickness of the piezoelectric patches was 1.2–1.4 mm, the designed device gained the best energy harvest performance with a peak voltage of 15–40 V. Works in this paper provide theoretical support and design reference for the application of the piezoelectric material in the drilling field.
