Semiconductor devices - Measurement and evaluation methods of kinetic energy harvesting devices under practical vibration environment - Part 1: Arbitrary and random mechanical vibrations
IEC 63150-1:2019 specifies terms and definitions, and test methods for kinetic energy harvesting devices for one-dimensional mechanical vibrations to determine the characteristic parameters under a practical vibration environment. Such vibration energy harvesting devices often have their own non-linear mechanisms to efficiently capture vibration energy in a broadband frequency range. This document is applicable to vibration energy harvesting devices with different power generation principles (such as electromagnetic, piezoelectric, electrostatic, etc.) and with different non-linear behaviour to the external mechanical excitation.
Dispositifs à semiconducteurs - Méthodes de mesure et d’évaluation des dispositifs de captage d’énergie cinétique dans un environnement de vibrations concret - Partie 1: Vibrations mécaniques arbitraires et aléatoires
L’IEC 63150-1:2019 spécifie les termes et les définitions, ainsi que les méthodes d’essai pour les dispositifs de captage d’énergie cinétique pour des vibrations mécaniques unidimensionnelles, et ce afin de déterminer les paramètres caractéristiques dans un environnement de vibrations concret. Ces dispositifs de captage d’énergie cinétique possèdent souvent leurs propres mécanismes non linéaires qui permettent de capter efficacement l’énergie de vibration dans une plage de fréquences à bande large. Le présent document s’applique aux dispositifs de captage d’énergie de vibration correspondant à différents principes de génération d’énergie (électromagnétique, piézoélectrique, électrostatique, etc.) et à différents comportements non linéaires en réponse à l’excitation mécanique extérieure.
