TL;DR: In this paper, a piezoelectric MEMS energy harvesting cantilever with low resonant frequency and wide operation bandwidth was designed, microfabricated, and characterized, where the whole chip was assembled onto a metal carrier with a limited spacer such that the operation frequency bandwidth can be widened to 17 Hz at the input acceleration of 1.0 g during frequency upsweep.

TL;DR: In this article, the authors presented the design, microfabrication, modeling and characterization of a piezoelectric energy harvester (PEH) system with a wide operating bandwidth introduced by mechanical stoppers.

TL;DR: In this article, two MEMS-based EH systems with wideband operation frequency range and capability of converting random and low-frequency vibrations to high-frequency self-oscillations have been proposed.

TL;DR: In this paper, a S-shaped piezoelectric PZT cantilever is microfabricated for scavenging vibration energy at low frequencies (<30 Hz) and low accelerations (<0.4g).

TL;DR: In this article, the authors developed a simple method for whole field out-of-plane displacement measurement using only one camera and employed digital image correlation (DIC) to calculate an apparent inplane displacement field which is introduced by magnification change due to an unknown out of plane displacement.
