The micromanipulator is a precision instrument for the manipulation and positioning of microscale and nanoscale structures. Its core function is to allow highly accurate control of microneedles or microforceps under optical observation, enabling precise three-dimensional positioning and movement. The fundamental principle of the system is the use of piezoelectric stick-slip actuators for sub-micrometer movements, integrated with high-magnification optical imaging real-time visualization while performing precise manipulations. This instrument is important for experiments requiring delicate manipulation of nanostructures such as nanomembranes or nanowires.
