In this paper preliminary results from investigations of the proof of concept of a nonlinear (vibrational) bistable inductive energy harvester are presented. The main idea proposed through this paper is to exploits the benefits of the snap-through buckling configuration in terms of capability to scavenge energy from wide band vibrations and the possibility to use the beam switching between its stable...
An autonomous bistable MEMS sensor for noninvasive monitoring of AC electrical currents is proposed in this work. The main idea is presented together with simulations and feasibility study. The sensor is composed of a piezoelectric cantilever beam equipped with two permanent magnets having opposed magnetization (one on its free end and one external and fixed) in order to achieve bistable behaviour...
In this work a novel inertial sensor is presented, which can be used as a low band accelerometer, a vibration sensor or an inclinometer. The device consists of a glass plate filled with deionized water surrounding a small volume of ferrofluid; a permanent magnet is used to fix the position of the ferrofluidic mass in a compliant position. The effect of an external stimulus can be estimated by measuring...
