Carbon nanotube based electrostrictive element

摘要

An carbon nanotube based electrostrictive element includes two electrostrictive layers spaced with each other, an electrical connector, and two electrodes. The two electrostrictive layers are electrically connected to each other at a first side, and spaced and insulated from each other at a second side via the electrical connector. The two electrodes are located at the second side and electrically connected respectively to the two electrostrictive layers.
