We here present a method for measuring human physical activity, which is based on detecting the electrostatic induction current generated by the walking motion under non-contact and non-attached conditions. A theoretical model for the electrostatic induction current generated because of a change in the electric potential of the human body is also proposed. By comparing the obtained electrostatic induction current with the theoretical model, it becomes obvious that this model effectively explains the behavior of the waveform of the electrostatic induction current. The normal walking motions of daily living are recorded using a portable sensor measurement located in an ordinary house. The obtained results show that detailed information regarding physical activity such as a walking cycle can be estimated using our proposed technique. This suggests that the proposed technique can be successfully applied to the estimation of human physical activity.

我们在此提出一种测量人体身体活动的方法，该方法基于检测非接触和非附着条件下步行运动产生的静电感应电流。还提出了由于人体电位变化而产生的静电感应电流的理论模型。通过将获得的静电感应电流与理论模型进行比较，可以看出该模型有效地解释了静电感应电流波形的行为。日常生活中的正常步行动作是使用位于普通房屋中的便携式传感器测量记录的。获得的结果表明，可以使用我们提出的技术来估计有关身体活动（例如步行周期）的详细信息。这表明所提出的技术可以成功应用于人体活动的估计。
