1. A sensor comprising:
a structure body configured to be deformable by an external force;
an electrode configured to be able to be attached to an arbitrary position of the structure body;
a determination unit configured to determine one deformation state of the structure body from multiple deformation states of the structure body based on a change in impedance measured using the electrode, for the structure body arbitrarily deformed by an object;
an output unit configured to output a signal based on the one deformation state of the structure body where the electrode is not disposed to an external device; and
an insulating shield member provided on a contact surface of the structure body with the object,
wherein the shield member has a set of openings at which the object comes in contact with the structure body, wherein the determination unit is configured to distinguish the multiple deformation states based on contacts with the set of openings.
