Abstract

The invention discloses an electrothermal micro-drive control optical path on-off device based on a U+V structure, and belongs to the technical field of MEMS micro-drivers. The device includes a driving mechanism and a locking mechanism, wherein the driving mechanism includes a driver composed of N U-shaped cantilever beams in cascade, N pairs of U-shaped cantilever beam anchor points, and N pairs of U-shaped cantilever beam electrode patches; the locking mechanism It includes a V-shaped cantilever beam array composed of M V-shaped cantilever beams, two V-shaped cantilever beam anchor points and two V-shaped cantilever beam electrode patches. By applying a voltage on the electrode sheet, the driving mechanism can be reliably locked in the non-driving or driving state, and the effective on-off control of the high-energy optical path can be realized. Compared with other micro-drive methods, the present invention adopts the logical cooperation of U-shaped cantilever beam electrothermal micro-drive mechanism and V-shaped cantilever beam locking mechanism, which has high driving reliability, low energy consumption, low cost and good system compatibility. A MEMS driver with excellent performance.

Description

technical field [0001] The invention belongs to the technical field of MEMS micro-drivers, in particular to an electrothermal micro-drive control optical path on-off device based on a U+V structure. Background technique [0002] MEMS micro-actuator is a key technology in micro-electromechanical systems, mainly including electrostatic drive, electromagnetic drive, electrothermal or thermal expansion drive, piezoelectric drive and intelligent material drive. Electrostatic drive uses the Coulomb force of electrostatic charge to generate attraction or repulsion to cause displacement of the driver. It has simple structure, convenient control, good system integration and manufacturability, large action stroke and high response frequency, but the required driving voltage is high, and the higher voltage It will cause the insulation layer between the electrode plates to be broken down, and long-term work will cause the accumulation of charges, which will affect the working stability ...
