Abstract

The invention provides a MEMS inertial switch with adjustable threshold, comprising: an upper sensing electrode configured to move toward the lower sensing electrode under the action of inertia, and forms a pulse induction signal when in contact with the lower sensing electrode; The electrode is configured to be fixed with the shell, and forms a pulse induction signal when in contact with the induction upper electrode; the electromagnetic attraction device is configured to generate a magnetic field after passing in a current, and the magnetic field generates orientation induction on the induction upper electrode The force of the lower electrode, the strength and direction of the magnetic field change with the change of the current.

Description

technical field [0001] The invention relates to the technical field of inertial switches, in particular to a MEMS inertial switch with adjustable threshold. Background technique [0002] In the fields of aerospace, automobile industry, inertial navigation, ammunition safety and control system, automobile detection, torpedo control and other fields, various new technologies are constantly emerging, and all kinds of detection and control equipment are moving towards the direction of miniaturization, low energy consumption and intelligence develop. In this situation, it is required that the used sensing elements and actuating elements not only meet the requirements of miniaturization, but also provide reliable stability. Micro-inertial components based on MEMS (Micro-Electro-Mechanical System, Micro-Electro-Mechanical System) technology came into being based on the above reasons, and give full play to their advantages of being small, flexible and intelligent. [0003] Micro-E...
