For improving transfusion safety, a smart blood bag management system using a load-integrated U-shaped nearfield antenna (LUNA) array is proposed. The system consists of four LUNAs for ID sensing with blood information and a switching circuit for the sensing of blood bag localization. The proposed system can be used to prevent the mishandling of blood transfusions and to manage blood bags remotely and effectively.
