本研究描述了用于评估日常体力活动的三轴加速度计(TA)和便携式数据处理单元的发展。TA由三个垂直安装的单轴压阻式加速度计组成，可用于记录覆盖人体加速度幅度和频率范围的加速度，仪器间和测试-再测试表明，TA的偏移量和灵敏度在每个测量方向上是相等的，并在两个测量日内保持不变，横向灵敏度在每个测量方向上有显著差异，但不影响加速度计的输出(
The present study describes the development of a triaxial accelerometer (TA) and a portable data processing unit for the assessment of daily physical activity. The TA is composed of three orthogonally mounted uniaxial piezoresistive accelerometers and can be used to register accelerations covering the amplitude and frequency ranges of human body acceleration, Interinstrument and test-retest experiments showed that the offset and the sensitivity of the TA were equal for each measurement direction and remained constant on two measurement days, Transverse sensitivity was significantly different for each measurement direction, but did not influence accelerometer output (
