Highly Sensitive Inertial Micro-Switch for Achieving Adjustable Multi-Threshold Acceleration

Simulation Study of Inertial Micro-Switch as Influenced by Squeeze-Film Damping and Applied Acceleration Load

Squeeze-film damping and acceleration load are two major issues in the design of inertial micro-switches. In order to deeply and systematically study these two issues, this paper proposes a typical vertically-driven inertial micro-switch, wherein the air and electrode gaps were chosen to design the required damping ratio and threshold value, respectively. The switch was modeled by ANSYS Workben...

Multi-Service Highly Sensitive Rectifier for Enhanced RF Energy Scavenging

Due to the growing implications of energy costs and carbon footprints, the need to adopt inexpensive, green energy harvesting strategies are of paramount importance for the long-term conservation of the environment and the global economy. To address this, the feasibility of harvesting low power density ambient RF energy simultaneously from multiple sources is examined. A high efficiency multi-r...

A Low-G Silicon Inertial Micro-Switch with Enhanced Contact Effect Using Squeeze-Film Damping

Contact time is one of the most important properties for inertial micro-switches. However, it is usually less than 20 μs for the switch with rigid electrode, which is difficult for the external circuit to recognize. This issue is traditionally addressed by designing the switch with a keep-close function or flexible electrode. However, the switch with keep-close function requires an additional o...

Multi-rank Method: Achieving Projection Transformation with Adjustable Accuracy and Speed

In the field of GIS, it is frequently required to carry out projection transformation of massive raster maps or remote sensing images. In this paper, a method named multi-rank method is presented. It is able to achieve projection transformation with adjustable accuracy and speed. All the points in a map or image are divided into four ranks. Rank-4 points, which scatter in the map, are transform...
