Graphene wristband is one of the applications of artificial intelligence in medical field. It uses the conductivity and flexibility of graphene materials, combined with artificial intelligence technology to achieve accurate blood pressure measurement and data acquisition. The advantage of this technology is that it can be worn comfortably and realize continuous monitoring, thus improving the accuracy and reliability of data. The application of graphene wristbands can also liberate patients from going to the hospital for testing frequently, thus reducing the pressure on medical resources. The appearance of graphene wristband is a great progress in the medical field, which will bring more innovation and development to the medical and health field.
