Abstract

In wearable electronics, autonomous sensor can potentially ease the usage of bulky battery and eventually lead to a sustainable system. In this paper, polyvinylidene fluoride (PVDF) piezoelectric film-integrated dual-gate thin-film transistor (TFT) is utilized to monitor human vital signs such as heart rate or impulse rate. The voltage generated by the PVDF from the impulse itself drives the TFT that rectifies and converts impulse signal to the weak current signal feeding to the low-noise amplifier. The preliminary results of such device in addition to system design of chip-based sensor-integrated RFID tag are addressed to unveil the promising applications in wearable electronics.
采用自主pvdf集成双栅薄膜晶体管进行心率/脉冲监测
在可穿戴电子产品中,自主传感器有可能减轻笨重电池的使用,并最终形成一个可持续发展的系统。本文利用聚偏氟乙烯(PVDF)压电薄膜集成双栅薄膜晶体管(TFT)监测人体心率、脉搏率等生命体征。PVDF从脉冲本身产生的电压驱动TFT, TFT将脉冲信号整流并转换为弱电流信号,馈送到低噪声放大器。本文介绍了该装置的初步研究结果以及基于芯片的传感器集成RFID标签的系统设计,以揭示其在可穿戴电子产品中的应用前景。
