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, the static characteristics of an electrostatically-actuated torsional micromirror based on the parallel-plate capacitor model are analyzed and the relationship between rotation angle and driving voltage is also determined, leading to the revealment of the direct relationships of the electrode size with the snapdown angle and the maximum driving voltage.

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: A novel method to encrypt a color image based on Arnold transform (ART) and interference method that encrypts each channel into two random phase masks based on the ART and interfered method is proposed.
