The behavior of specific force receivers, defined as active or dynamic sensors, when affected by gravitational, linear and centrifugal accelerations is theoretically investigated. The capability of these active sensors A To sense gravitational, linear and centrifugal accelerations B to measure the gradient of a gravitational field C to determine the direction of the gravity gradient or the local vertical D to sense the state of a body falling freely, for example, along a gradient line is examined, taking as an example a miniaturized, commercially available sensor. This investigation is primarily concerned with the physics of the suggested types of active sensors and of one or more dimensional assemblies of such sensors, their development, improvement of their sensitivity and their testing by methodic experiments and accurate measurements. It is hoped that such experimental investigations will contribute useful information concerning the problem of gravity gradient sensing and measurement. Author
