我们的电子秤使用生物电阻抗分析 (BIA) 方法。电子秤发送微弱的电流来测量您的阻抗,然后用阻抗来估算体内水分总量 (TBW)。
体内水分总量可用于估算去除脂肪后的体重,即体重减去脂肪质量。

注意:
脂肪含量 + 骨质量 + 肌肉质量 = 100% 身体成分 = Your weight
由于肌肉和脂肪中有水分,在计算身体成分时,水分含量不能添加到其他指标中。

 

Important: Withings has not evaluated the accuracy of the measurement in patients with scar tissues, so Withings cannot guarantee that scar tissues do not have an effect on the accuracy of the measurement in a population of patients with scar tissues.

However Withings is not aware of any contraindication to the use of bioimpedance in the presence of scar tissues. In addition, it does not seem probable that scar tissues will affect the accuracy for a couple of reasons:

  1. The scar tissues are made of collagen fibers as normal skin. The difference is in the orientation of the fibers, which should not have an impact on the bioimpedance measurement.
  2. The electric signals used in a bioimpedance measurement propagate deep into the tissues, so that they should not be significantly affected by modifications of the composition of superficial tissues, if any.
