The main research directions that provide the scientific collaboration LIGO-Virgo with the aim of increasing the sensitivity of interferometric gravitational-wave detectors, as well as the next generation detectors currently being developed, are presented. Suspended test masses, the reflective coatings of which form the mirrors of the interferometer, are the sensitive elements of the gravitational-wave detector. These studies are related to similar studies, which are aimed at the development of MEMS gravimeters of a new generation. The issues of creating and increasing the sensitivity of such gravimeters are considered in the second part of the work.

Key words: interferometric detector of gravitational waves, test masses, gravimeter.
