    • Provided is an unconstrained wearable spirometer apparatus. The apparatus includes a variable resistor including a conductive yarn, the length of which changes according to a change in circumference of one's chest when breathing, and having a resistance which changes according to a change in length of the conductive yarn, a resistance-voltage converter converting the resistance of the variable resistor into a voltage, an analog-digital converter converting the voltage in an analog-digital manner, and digitizing the converted results, a cross-sectional capacity calculator calculating changes in cross-sectional capacity of one's chest according to the digitized voltage, an adder adding the calculated changes in cross-sectional capacity and calculating lung capacity, and a transmitter externally transmitting the calculated lung capacity information. Therefore, lung capacity can be measured by wearing such an apparatus in the form of clothing without the use of an external apparatus or device.
    • 提供了一种无约束的可穿戴式肺活量计装置。 该装置包括可变电阻器,其包括导电纱线,其长度根据呼吸时胸部周围的变化而变化,并且具有根据导电纱线的长度变化而变化的电阻,电阻 - 电压转换器 将可变电阻器的电阻转换成电压,以模数转换方式转换电压的模拟数字转换器,对转换的结果进行数字化;横截面积计算器,计算胸部横截面积的变化,根据 数字化电压,加法器,其加上计算出的横截面积变化量和计算肺容量,以及外部传输所计算的肺容量信息的发射器。 因此,可以通过在不使用外部装置或装置的情况下穿着衣服形式的装置来测量肺容量。
