1. A flexible body comprising one or more flexible units, wherein each of the flexible units comprises: a first electrode, a second electrode, an electroactive polymer layer, and a thin film transistor, wherein a source electrode or a drain electrode of the thin film transistor is electrically connected to the second electrode;
wherein the first electrode and the second electrode are configured to provide an electric field acting on the electroactive polymer layer, and the electroactive polymer layer is configured to deform in response to the electric field provided by the first electrode and the second electrode; and
wherein the electroactive polymer layer comprises an ion-type electroactive polymer, and the flexible unit further comprises an electrolyte solution layer in contact with the electroactive polymer layer,
wherein the electroactive polymer layer comprises N electroactive polymer sub-layers, the electrolyte solution layer comprises N−1 electrolyte solution sub-layers, and each of the electrolyte solution sub-layers is arranged between two adjacent electroactive polymer sub-layers, wherein N is an integer greater than 1.
