微纳电子技术

详细阐述了一种微型电磁继电器的设计和初步研制过程。该微继电器主要由电极、悬臂梁结构和电磁线圈组成。设计过程中考虑了微继电器打开、闭合时电磁力、静电力和悬臂梁回复力之间的制约关系,即微继电器打开时悬臂梁回复力应大于接触部位的静电力;闭合时电磁力应大于悬臂梁的回复力。从而推算出电磁线圈的安匝数和悬臂梁结构尺寸的合理范围并选定了合适的参数,用UV-LIGA技术初步制作了这种微型电磁继电器的主要部分。

In this article we discuss the design of a kind of electromagnetic microrelays and the prime process of fabrication.The microrelay is consist of electrodes,a micro beam and coils.We calculate the electromagnetic force,the electrostatic force and the restore force of the micro beam when the microrelay operating and choose the parameters of the microrelay.
