摘　　要：柔性传感器能够实现压力、应变、温度、湿度及气体等与人体健康相关信号多功能识别及监测,在可穿戴人工智能设备的开发中展现出巨大的应用前景。本文综述了具有多种模式监测功能的柔性电化学式传感器领域最新研究成果,包括双模式传感器、三模式传感器和多模式传感器;重点介绍了传感器实现多功能监测的途径和传感机理。研究表明,多模式传感性的实现方法主要包括结构设计和多功能材料制备两种。而基于先进功能材料(包括纳米金属、纳米碳及导电聚合物)和柔性基体材料(如水凝胶、气凝胶及弹性聚合物)所制造的柔性多功能复合材料可有效降低多模式传感器的复杂性。最后,对比并指出了不同类型的功能材料在制造多功能柔性传感器中的特点与优势,为多功能柔性传感器的研究提供借鉴意义。In order to mimic the multifunctional sensing function of skin, a large number of flexible and stretchable sensor arrays have been constructed based on different conduction mechanisms and structural designs. The flexible sensors that can realize multifunctional identification and monitoring of physiological signals related to human health, such as pressure, strain, temperature, humidity and gas, show the great application prospects in the development of wearable artificial intelligence devices. In his paper the latest research achievements in the field of flexible electrochemical sensors with multi-mode monitoring were reviewed. The sensor can detect two stimuli(pressure-strain, pressure/strain-temperature, pressure/strain-humidity, pressure/strain-gas), three stimuli(pressure-strain-temperature, pressure-temperature-humidity, pressure-temperature-gas, etc.) and more than three kinds of stimuli(pressure-strain-temperature-humidity, etc.), which are defined as two-mode sensor, three-mode sensor and multi-mode sensor respectively. This paper focused on the pathway and sensing mechanism of the sensor to achieve multifunctional monitoring. The analysis shows that the methods to achieve multifunctional sensing properties mainly include both structural design and multifunctional material preparation. The flexible multifunctional composites fabricated based on advanced functional materials(including nanometals,nanocarbon and conducting polymers) and flexible matrix materials(such as hydrogels, aerogels and elastic polymers) can effectively reduce the complexity of multi-mode sensors. The characteristics and advantages of different types of functional materials in the fabrication of multifunctional flexible sensors are compared and pointed out to provide implications for the design of multifunctional sensors.
