This article reviews on the development of a new category motion sensors for vibration monitoring including linear and angular accelerometers based on molecular electronic transducer (MET) technology. This technology utilizes liquid not only as an inertial mass but also as one of the main elements in the conversion of mechanical motion into electric current. It is possible to achieve signal amplification close to 108. Motion sensors demonstrate wide frequency and dynamic range and sensitivity that are one to two orders of magnitude better than MEMS devices of the same size. They can provide an alternative paradigm in development of motion sensors in wide variety of applications including monitoring systems of complex engineering structures, seismic analysis of bridges and buildings, remote sensing devices, structural behavior and structure wind excitation measurement.
