体力活动（PA）是评估人类暴露于环境的重要因素。本文提出了一种基于ZigBee的无线可穿戴多传感器集成测量系统（WIMS），用于现场PA测量。两个加速度计，压电位移传感器，和紫外线（UV）传感器已被用于身体活动评估。详细分析了硬件设计和嵌入式程序控制，实现了高效的数据采集和传输，紧凑的设计，延长了电池寿命，以满足自由生活条件下PA评估的要求。WIMS的初步测试证明了设计的功能性，而WIMS与电磁振动器上的有线版本的性能比较证明了信号的有效性。
Physical activity (PA) is important for assessing human exposure to the environment. This paper presents a ZigBee-based Wireless wearable multi-sensor Integrated Measurement System (WIMS) for in-situ PA measurement. Two accelerometers, a piezoelectric displacement sensor, and an ultraviolet (UV) sensor have been used for the physical activity assessment. Detailed analysis was performed for the hardware design and embedded program control, enabling efficient data sampling and transmission, compact design, and extended battery life to meet requirements for PA assessment under free-living conditions. Preliminary testing of the WIMS has demonstrated the functionality of the design, while performance comparison of the WIMS with a wired version on an electromagnetic shaker has demonstrated the signal validity.
