Abstract: Miniaturization, low power consumption have always been the design goals of multi-axis sensor in the field of smart wearables. This design consists of the wireless bluetooth MCU, micro-antenna, wireless charging unit, multi-axis sensor and so on, achieves micro-system control, information collection of movement and gesture, wireless data transmission, wireless charging and other functions. The product size is 34.00×27.00×10.50 mm, the working time is more than 30 hours. The product can be deployed on the human body and related parts of the device as an independent terminal, and it collects movement and gesture data to upload to the host server. And the backend APP and algorithm  can realize motion status monitoring and data analysis. It can also be integrated as modules into electronic terminal equipment to facilitate the miniaturization design of terminal.

Keywords: miniaturization; low power consumption; multi-axis sensor; wireless bluetooth; wireless charging; movement monitoring
