| titleOfInvention | Application of two-dimensional material in speed sensor |
| abstract | The invention discloses an application of a two-dimensional material in a speed sensor, wherein the two-dimensional material has in-plane spontaneous polarization, a double-layer stacking structure of the two-dimensional material can generate ferroelectric-antiferroelectric phase change under mechanical motion, the application of the ferroelectric-antiferroelectric phase change based on the double-layer two-dimensional material is also disclosed, and the speed sensor comprising the double-layer two-dimensional material is further disclosed. The invention utilizes the ferroelectric phase transition of the two-dimensional material to improve the mechanical displacement measurement precision of the nanometer scale, drives the interlayer slippage of the two-dimensional material by the external action, realizes the mutual conversion of the two-dimensional material from the ferroelectric phase and the antiferroelectric phase, converts the mechanical energy of the interlayer slippage of the two-dimensional material into the bidirectional pulse current, is simultaneously suitable for the mechanical movement in the one-way and back-and-forth modes, can reflect the interlayer mechanical slippage speed by measuring the size and the frequency of the pulse current, has larger output current, is convenient for measuring the interlayer relative movement speed, and has wide measurement speed range. |
