我们设计并分析了一种用于监测呼吸的柔性非接触式电磁传感器。本文介绍了传感器的设计和预期的灵敏度，我们优化设计元件的理论模型。该设备的主要应用是在非侵入性睡眠监测，它有可能是有用的检测成人和婴儿呼吸暂停。通过在肺内感应涡流来监测呼吸期间肺的电导率变化。该传感器由一个小线圈组成，既充当发射器又充当接收器。计算传感器对呼吸变化的理论灵敏度，并在模型的假设范围内与测量结果相对应。
We design and analyse a flexible non-contact electromagnetic sensor for monitoring breathing. This paper presents the sensor design and the theoretical model for the expected sensitivity from which we optimize design components. The primary application of this device is in non-invasive sleep monitoring and it has the potential to be useful for detection of both adult and infant apnea. The conductivity changes of the lungs during breathing are monitored by inducing eddy currents within them. The sensor consists of a small coil that acts as both a transmitter and a receiver. The theoretical sensitivity of the sensor to breathing changes is calculated and corresponds within the assumptions of the model to the measured results.
