This invention discloses a method for rapidly preparing metal microelectrodes using vacuum filling and mechanical exfoliation, relating to the field of micro-nano manufacturing. This method significantly reduces the viscosity of the liquid metal and its flow resistance by preheating the PDMS-hydrosol bonding interface at high temperature. Simultaneously, preheating intensifies the thermal motion of gas molecules within the microchannel, facilitating rapid gas expulsion. This allows for complete filling of the microchannel within a short vacuum holding time (at least 1 minute), significantly shortening the vacuum holding time compared to the traditional 20-30 minute process, thus greatly improving preparation efficiency.

The application relates to the technical field of acceleration detection by using optical force, and discloses an optical force accelerometer based on spin cooling and a use method, which realizes acceleration detection by using laser-suspended microspheres, and improves detection precision by using the spin cooling effect of the microspheres in an optical field to inhibit thermal motion of the microspheres. Laser is processed into circularly polarized light suitable for capture and rotation driving by a laser modulation unit, and is input into a capture cooling unit; the capture cooling unit utilizes a potential well formed by an optical field to realize capture and rotation cooling of microparticles, simultaneously outputs laser carrying state information of the microparticles, and a displacement detection unit realizes acceleration response output by analyzing and monitoring the displacement state of the microparticles in real time through analysis of outgoing laser; a test unit provides auxiliary illumination and completes visual observation of behaviors of the microparticles, and together forms an optical capture and measurement system. The spin cooling method is adopted to realize cooling of a sensitive mass of the optical force accelerometer, the structure of a cooling system is simplified, performance requirements are reduced, practical potential is high, and cost is low.
