The invention discloses an intelligent T-shirt based on multi-mode sensing and structure optimization, the intelligent T-shirt comprises a T-shirt body, a flexible IMU module, a flexible
textile electrode, a
yarn sensing belt and a main control module, the flexible IMU module is carried on the T-shirt body to collect posture information of a user; the flexible
textile electrode is arranged in a chest area of the T-shirt body to collect
heart rate information of a user; the
yarn sensing belts are arranged at the
chest circumference position and the belly position of the T-shirt body so as to collect
breathing information of a user. The main control module is electrically connected with the flexible IMU module, the flexible
textile electrode and the
yarn sensing strip, obtains and fuses posture information,
heart rate information and
breathing information, and generates user
monitoring data. According to the method, the user data can be collected from
multiple modes including the posture information, the
heart rate information and the
breathing information of the user, and more comprehensive and accurate user
monitoring data is generated; meanwhile, the sensing modules are flexible modules, so that the wearing comfort is improved.
