可穿戴和可植入的压力传感器对个性化健康监测的需求很大。低工作电压、低功耗的压力传感器是节能设备的理想选择。有机电离电子器件，如有机电化学晶体管(OECTS)，在低功耗生物电子传感应用方面显示出巨大的潜力。电子和离子的导电能力，加上它们的低工作电压，使得OECTS在不同的生物传感领域得到了广泛的应用。然而，尽管有这些优点，但在压力传感应用方面还没有得到证实。这是因为大多数卵巢是用水电解液浇注的，它不能对外部压力做出反应。本文提出了一种基于光电转换的低功耗离子压力传感器，其中离子水凝胶被用作固体栅极介质。该器件工作电压小于1V，功耗在~10~10μW之间，灵敏度在1~10kPA−1之间可调。这项工作为开发低功耗电离压力传感器和生物传感应用奠定了基础。
Wearable and implantable pressure sensors are in great demand for personalized health monitoring. Pressure sensors with low operation voltage and low power-consumption are desired for energy-saving devices. Organic iontronic devices, such as organic electrochemical transistors (OECTs), have demonstrated great potential for low power-consumption bioelectronic sensing applications. The ability to conduct both electrons and ions, in addition to their low-operation voltage has enabled the widespread use of OECTs in different biosensing fields. However, despite these merits, OECTs have not been demonstrated for pressure sensing applications. This is because most OECTs are gated with aqueous electrolyte, which fails to respond to external pressure. Here, a low power-consumption iontronic pressure sensor is presented based on an OECT, in which an ionic hydrogel is used as a solid gating medium. The resultant iontronic device operated at voltages less than 1 V, with a power-consumption between ~ 101-103 μW, while maintaining a tunable sensitivity between 1 ~ 10 kPa−1. This work places OECTs on the frontline for developing low power-consumption iontronic pressure sensors and for biosensing applications.
