Abstract

The invention discloses a high impact inertia micro-fluid power connection switch and a manufacturing method thereof. The high impact inertia micro-fluid power connection switch comprises a base, a cover plate, a metal electrode, a micro-channel and metal droplets. The cover plate is arranged on the upper end of the base. The micro-channel is arranged on the base. The metal electrode is arranged on the cover plate. The micro-channel comprises a U-shaped liquid storage tank, capillary valves and an air guide channel. The metal droplets are arranged in the U-shaped liquid storage tank. The firstcapillary valve is connected with the U-shaped liquid storage tank. The second capillary valve is connected with the first capillary valve, and the other end is connected with the third capillary valve. The third capillary valve is connected with the second capillary valve, and the other end is connected with the fourth capillary valve. The fourth capillary valve is connected with the third capillary valve. The fifth capillary valve is connected with the sixth capillary valve. The other end of the sixth capillary valve is connected with the seventh capillary valve. The seventh capillary valveis connected with the sixth capillary valve, and the other end is connected with the eighth capillary valve. The eighth capillary valve is connected with the seventh capillary valve, and the other end is connected with the U-shaped liquid storage tank. The fourth capillary valve and the fifth capillary valve are connected through the air guide channel. The switch can identify the fuze ambient force.

Description

technical field [0001] The invention belongs to the technical field of microfluidic chips, in particular to a high-impact inertial microfluidic power switch and a manufacturing method thereof. Background technique [0002] The microfluidic inertia switch is a new type of switch proposed on the basis of micromechanical inertial switch and microfluidic technology. The microfluidic inertia switch is a system that manipulates a small volume of fluid to circulate in tiny channels or components, where the size of the channels and components is tens to hundreds of microns. Different from the traditional micromechanical switch, the microfluidic inertial switch generally uses metal droplets as the working fluid, and its working principle is that when the metal droplets are subjected to a certain acceleration load, they will reach the position of the fixed signal electrode through the microchannel, and then Turn on the switch. This working mode can overcome the problems of tradition...
