The Center for Gravitational Experiments (CGE) at Huazhong University of Science and Technology (HUST), has been focusing on gravitational experiments, precision gravity measurements and related theories since 1983. CGE-HUST gained worldwide fame for its gravitational constant measurements with record precision published in Nature, 2018. Currently, MEMS-based gravity measurement apparatus and their micro-fabrication techniques are the emerging research topics at CGE-HUST.
