Small neutrino detectors have a wide range of application prospects in reactor monitoring, submarine detection and geophysics research. This paper summarizes the types of neutrinos and detection principles, followed by the development status of detection technologies at home and abroad, including experiments based on inverse beta decay and coherent scattering experiments of neutrinos. Finally, the development of small neutrino detectors is reviewed and differences between different countries and the future development of small neutrino detectors in China are also summarized.
