Claims
- 1. An electromechanical converting device for converting electric energy into mechanical energy, comprising a ferroelectric liquid crystal panel having a first electrode; a second electrode disposed in opposing relation to said first electrode; a ferroelectric liquid crystal interposed between said first and second electrodes; and a first alignment layer formed between said ferroelectric liquid crystal and said first electrode; electric signal generating means connected to apply electric signals between said first and second electrodes; whereby said ferroelectric crystal panel oscillates in response to said electric signals, and movable means mounted to be moved in correspondence with said oscillation of said ferroelectric liquid crystal panel.
- 2. The electromechanical converting device of claim 1 further comprising a second alignment layer between said second electrode and said ferroelectric liquid crystal.
- 3. The electromechanical converting device of claim 2 wherein said first alignment layer and said second alignment layer have homogeneous alignments that are neither parallel nor anti-parallel with respect to one another.
- 4. The electromechanical converting device of claim 2 wherein said first alignment layer and said second alignment layer are comprised of different materials.
- 5. The electromechanical converting device of claim 2 wherein said first alignment layer attracts spontaneous polarization of said ferroelectric liquid crystal, and said second alignment layer repulses spontaneous polarization of said ferroelectric liquid crystal.
- 6. The electromechanical converting device of claim 1 wherein said alignment layer has homogeneous alignment resulting from strong rubbing.
