Abstract

The invention relates to a small-size test device for mechanical and electrical coupling characteristics and belongs to a mechanical-electrical integrated precise scientific instrument. The small-size test device mainly comprises a Z axis autoexec adjusting mechanism, an XY autoexec adjusting mechanism, a piezoelectric precise driving pressing unit, a load signal detection unit, a displacement signal detection unit and a current signal detection unit, wherein the Z axis autoexec adjusting mechanism is installed on a base; the XY autoexec adjusting mechanism is installed on an upper supportingplate; the piezoelectric precise driving pressing unit is connected to a micro-slipway; the precise displacement sensor is fixedly connected to the front end side face of the piezoelectric precise driving pressing unit; a strain foil rood beam for detecting a load signal is installed on a worktable of the Z axis autoexec adjusting mechanism; and the change of the electrical characteristic generated by materials in the test process is detected by using the principle of a diamond indenter anvil cell and a PCD (Polycrystalline Diamond) diamond indenter. The small-size test device provided by theinvention has the characteristics of compact structure, small volume and high precision and the like.

Description

technical field [0001] The present invention relates to a precision scientific instrument of electromechanical integration, in particular to a test device integrating macro drive, high-precision detection, mechanical properties of micro-nano materials, and mechanical and electrical coupling properties, especially a miniaturized mechanical and electrical coupling properties test device. Background technique [0002] The invention of the diamond anvil cell (abbreviated as DAC) is a technological revolution in the development of high-pressure technology. It is currently the only experimental device that can generate ultra-high hydrostatic pressure (higher than 100GPa). The strange phenomenon that materials will change under high pressure and ultra-high pressure has been generally recognized at home and abroad, and has been confirmed by many experiments. Through DAC, the transformation of metals and semiconductors, the transformation of electrons, and the transformation of mater...
