Problems solved by technology

However, the current testing of materials using probe systems is mostly carried out in an open test environment. The probes and test samples are directly placed in the air environment for testing, which makes it easier to load light fields, electric fields, magnetic fields, force fields and strains. field, but it is impossible to test in humidity conditions, vacuum environment, etc., and it is easily disturbed by the external environment, which affects the reliability, accuracy and precision of the test results

When other probe systems are tested in a closed environment, although vacuum and humidity control can be achieved, multiple physical fields such as electricity, magnetism, heat, force, and light cannot be simultaneously loaded: if the entire probe system and the test The materials are placed in a closed environment together, and the electric field, magnetic field, and thermal field will damage the electronic components in the probe system, which greatly limits the loading parameters such as physical field strength and frequency; if only the probe and the test material are placed in a closed environment In the process, it is difficult for the probe system to load the force field and the strain field. At the same time, the electric field, magnetic field, thermal field, force field, and light field will interfere with each other, and it is easy to affect each other during the test process, resulting in unreliable test results and insufficient accuracy.
