TL;DR: In this paper, the porosity distribution of the CGPC along the incident direction is nearly linear and the sound absorption characteristics of CGPCs were experimentally investigated and compared with those of uniform phononic crystals (UPCs) and discretely stepped phononic crystal (DSPCs).

TL;DR: In this article, the authors presented the new design and fabricating process of a packaged micro piezoelectric vibration energy harvester (PVEH), which was designed and optimized through finite element modelling and analysis.

TL;DR: The working mode stress–frequency theory of a double-ended tuning fork with an enhanced coupling beam is proposed, which is compatible with the simulation and experiment, and a unique piezoresistive detection method based on small axially deformed beams with a resonant status is proposed.

TL;DR: In this article, a V-shaped piezoelectric vibration energy harvester (V-PVEH) with impact stopper is proposed for low-frequency vibration and shock energy harvesting.

TL;DR: The experimental results showed that the proposed peninsula-island-based diaphragm structure had the potential to measure ultra-low absolute pressures with high sensitivity and good anti-overload ability in an atmospheric environment.
