A micropositioner is an instrument that is used to move small objects with a high degree of accuracy and precision. It is a synonym for several other terms, such as a micro-manipulator, a micro-positioning stage, a piezo stage, and a nano-positioner. Each of these terms describes an instrument that is similar to a micropositioner in its function and design. Micro-manipulators are typically used in biology and biomedicine to move small samples or cells for experiments. Piezo stages and nano-positioners are used in nanotechnology to move and manipulate nanoscale objects. These devices are essential tools in many scientific disciplines and industries where precision and accuracy are critical.
