中文摘要:

      针对普通干电极和医用湿电极应用于心电监测系统时存在的问题，制备了一种聚二甲基硅氧烷（polydimethylsiloxane，PDMS）基底上阵列金字塔结构的柔性电极。该电极通过阵列金字塔结构加大电极表面积，减小电极阻抗，并对心电信号处理电路、基于安卓端的APP等部分进行了设计，制作了便携式心电监测系统。实验结果表明，上位机可实时显示心电波形，同时，使用制备的柔性电极可以采集到较好的心电信号。

英文摘要:

      Aiming at the problem existing in the application of common dry electrode and medical wet electrode in electrocardiogram (ECG) monitoring system,a flexible electrode with pyramid array structure on polydimethylsiloxane (PDMS) substrate is prepared.The electrode increases surface area to reduces the electrode impedance through the array pyramid structure.The ECG signal processing circuit and APP based on Android terminal are designed,and a portable ECG monitoring system is made.The experimental results show that the upper computer can display the ECG waveform in real time,and the prepared flexible electrode can collect better ECG signals.
