本文报道了一种基于mems的压力传感器，该传感器仅使用一个传感元件即可同时测量血液脉搏波和呼吸。在该装置中，将一根薄硅胶管连接在一副眼镜的鼻垫上，其内部压力可以通过压阻悬臂测量。佩戴眼镜时，传感器装置的导管与受试者的角动脉和鼻腔同时接触，脉搏波和呼吸都会引起导管内压的变化。我们表明，可以分别提取脉冲波和呼吸作为传感器信号的低频和高频成分。
This paper reports a MEMS-based pressure sensor that can simultaneously measure the blood pulse wave and respiration by using only one sensing element. In the proposed device, a thin silicone tube whose inner pressure can be measured by a piezoresistive cantilever is attached to a nose pad of a pair of eyeglasses. When wearing the eyeglasses, the tube of sensor device is in contact with both the angular artery and the nasal cavity of the subject and both pulse wave and breath cause the tube's inner pressure to change. We show that it is possible to extract the pulse wave and respiration as the low frequency and high frequency components of sensor signal, respectively.
