介绍了一种采用生物相容性和柔性聚对二甲苯硅技术组装的无电池可穿戴式贴片心电图监测系统。该系统通过内置数字信号处理器（DSP）对采集到的心电信号进行处理并检测心律失常。一个NFC通信系统用于连接外部阅读器。该芯片还集成了一个亚阈值超低电压（ULV）升压转换器，用于从附着在胸部的热电发电机（TEG）收集人体热能，为ECG系统供电。升压变换器工作时没有外部启动电路，平均效率高达60%。组装的一体化系统实现了非常低的轮廓（< 0.9mm）；它包括一个CMOS芯片，两个SMD电感器（用于升压转换器）和两个聚对二甲苯金线圈（用于NFC通信系统）。柔韧的聚二甲苯模具提供了良好的附着力和皮肤舒适性。
A batteryless wearable ECG monitoring system-in-a-patch assembled by a biocompatible and pliable silicon-in-parylene technology is introduced. The system is capable of processing the acquired ECG signal and detecting arrhythmia by a built-in digital signal processor (DSP). An NFC communication system is used to interface the external reader. The silicon also integrates a sub-threshold ultra-low-voltage (ULV) boost converter to harvest body heat energy from a thermoelectric generator (TEG) attached to the chest to power up the ECG system. The boost converter operates with no external kick-off circuitry, and the average efficiency is up to 60%. The assembled all-in-one system achieves a very low profile (<;0.9mm); it includes one CMOS die, two SMD inductors (for the boost converter), and two in-parylene gold coils (for the NFC communication system). The pliable parylene mold provides excellent adhesion and skin comfort.
