We examined the charging characteristics of electrets using X-rays and vacuum UV irradiation for MEMS power generator. Surface potential increases as X-ray irradiation time and the charging rate varies for introduced gas species. VUV can form electrets within 2 sec due to the generation of large amount of ions/electrons.
