Abstract:

People's demand for sports and keeping fit ever increases, and requirements for comfort and intelligence of sportswear becomes high. This research worked on the design of intelligent sports bra facilitating the collection of various physiological parameters and motion information of the human body during exercise. Various small sensors and low-power control chips were employed to create the electronic system scheme and workflow of smart clothing. In this research, a basic intelligent sports bra was designed and developed through optimizing traditional sports bra, collecting information such as position, movement state, body temperature, and heart rate and perspiration parameters. The data was uploaded to the terminal by wirelessly to analyze the current physiological state and exercise effect of the human body for determining the health status, and provide early warning to the user through an intelligent terminal.

Key words: intelligent sports bra, microelectromechanical system sensor, heart rate belt of fabric, electronic monitoring system, data acquisition
