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.
身体活动（PA）对于评估人类与环境的接触情况很重要。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、一个压电位移传感器和一个紫外线（UV）传感器已被用于身体活动评估。对硬件设计和嵌入式程序控制进行了详细分析，实现了高效的数据采样和传输、紧凑的设计以及延长的电池寿命，以满足自由生活条件下 PA 评估的要求。WIMS 的初步测试证明了该设计的功能，而 WIMS 与有线版本在电磁振动台上的性能比较则证明了信号的有效性。
