This technology utilizes a liquid not only as an inertial mass, but also as one of the main elements in the conversion of mechanical motion into electric current. The amplification process is similar to that in a vacuum triode. Therefore, it is possible to achieve signal amplification close to 108. Motion sensors demonstrating wide frequency and dynamic range and sensitivity that are one to two orders of magnitude better than MEMS devices of the same size have been developed.<\/jats:p>","DOI":"10.3390\/s130404581","type":"journal-article","created":{"date-parts":[[2013,4,8]],"date-time":"2013-04-08T12:01:31Z","timestamp":1365422491000},"page":"4581-4597","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":89,"title":["Molecular Electric Transducers as Motion Sensors: A Review"],"prefix":"10.3390","volume":"13","author":[{"given":"Hai","family":"Huang","sequence":"first","affiliation":[{"name":"School of Electrical, Computer and Energy Engineering, Arizona State University, Tempe,  AZ 85287, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Vadim","family":"Agafonov","sequence":"additional","affiliation":[{"name":"Center of Molecular Electronics, Moscow Institute of Physics and Technology, Moscow 141700, Russia"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hongyu","family":"Yu","sequence":"additional","affiliation":[{"name":"School of Electrical, Computer and Energy Engineering, Arizona State University, Tempe,  AZ 85287, USA"},{"name":"School of Earth and Space Exploration, Arizona State University, Tempe, AZ 85287, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2013,4,8]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Pike, W.T., Standley, I.M., Karl, W.J., Kumar, S., Semple, T., Vijendran, S.J., and Hopf, T.
