摘要
Abstract
In order to meet the needs of daily sleep monitoring,a P(VDF-TrFE)/lead zirconate titanate(PZT)piezoelectric sensor based on high voltage electrospinning process is proposed and its performance is studied.Firstly,the fabrication and packaging process of P(VDF-TrFE)/PZT piezoelectric sensor are introduced.Then,its sensitivity,frequency response characteristics,transient response and stability are tested.The results show that good microscopic morphology is formed on the sensor.The sensitivity of the P(VDF-TrFE)/PZT piezoelectric sensor with 30％PZT mass fraction reaches 1.78 V/N,which is 2.5 times higher than that of the pure P(VDF-TrFE)piezoelectric sensor.In addition,it not only maintains stable piezoelectric output at low frequencies but also has a fast response time of 2 ms.Finally,the BCG signal is measured with a self-made P(VDF-TrFE)/PZT piezoelectric sensor and the sleep stage model is trained using by support vector machine(SVM).The average accuracy of the four-classification model is 72.5％,which provides a refer-ence for the selection of wearable sleep monitoring sensors.关键词
