We introduce a microwave cloak composed of smart metamaterials whose electromagnetic properties can be effectively changed by mechanical deformation. Against mechanical deformations, our smart metamaterials self-adjust own flexible elasto-electromagnetic crystal structure for obeying transformation optics rules. With this idea, we built microwave cloak made of flexible silicone rubber tube array and experimentally demonstrated self-adjustable carpet cloak in broadband ranges (8-12GHz) with variable deformations.
