Abstract: With the widespread application of MEMS technology in extreme radiation environments such as space exploration and nuclear engineering, the issue of radiation reliability has become increasingly prominent. The failure mechanisms of MEMS devices based on different working principles (electrostatic actuation, piezoresistive sensing, piezoelectric conversion, etc.) under radiation environments are systematically analyzed, with particular focus on the effects of ionizing radiation and displacement damage on device performance. A comprehensive review is presented on recent advances in radiation-hardening technologies, encompassing material optimization, structural design, and process improvements. Furthermore, addressing future application requirements in deep-space exploration and nuclear reactor monitoring, the development trends and research directions for radiation-hardened MEMS are proposed, providing valuable insights for the design and application of highly reliable MEMS devices.

Key words: MEMS, extreme radiation environment, radiation damage mechanism, radiation-hardening technology, reliability design
