Abstract
[Object] To provide a technology relating to a piezoelectric coil or the like capable of performing displacement sensing. [Solving Means] A piezoelectric coil with a sensor according to the present technology includes: a piezoelectric coil; and a sensor. The piezoelectric coil includes a coil-shaped core and one or more first piezoelectric members that are helical relative to the core, and is expandable and contractable in an expanding/contracting direction. The sensor detects a displacement due to expansion and contraction of the piezoelectric coil.
