| 摘要 | A sensor includes a first electrode, a second electrode, a ferroelectric element that is disposed between the first electrode and the second electrode and that has a ferroelectric film formed of a ferroelectric substance, and a detector configured to read an electric charge generated in the ferroelectric element. The detector performs reading by applying a first voltage for aligning polarization directions of the ferroelectric film and a second voltage for reversing polarization of at least part of the ferroelectric film whose polarization directions have been aligned. | ||
