智能可穿戴柔性可拉伸应变传感器的研究进展

Research Progress of Smart Wearable Flexible Stretchable Strain Sensor

柔性可拉伸应变传感器可以附着在人体表面上感知外部信号,具有轻便、低成本、高柔性、高拉伸性和高耐久性等优点。柔性可拉伸应变传感器的柔性基底材料通常导电性较差,导致柔性可拉伸应变传感器的灵敏度也较差。将具有优异电导率的导电聚合物和纳米材料等导电材料与柔性材料集成在一起,在保证良好柔性的同时可以极大的提高柔性可拉伸应变传感器的电导率和灵敏度。阐述了智能可穿戴柔性可拉伸应变传感器的研究进展及应用前景。

In recent years,with the continuous development of the smart wearable field,the flexible stretchable strain sensors capable of signal monitoring have great application potential in the fields of human motion mo-nitoring,health monitoring,wearable electronic devices and electronic skin.The flexible stretchable strain sensors can be attached to the surface of the human body to sense external signals,and have the advantages of lightness,low cost,high flexibility,high stretchability and high durability.The flexible base material of the flexible stretchable strain sensor generally has poor electrical conductivity,resulting in poor sensitivity of the flexible stretchable strain sensor.The combination of conductive materials such as conductive polymers and nanomaterials with excellent conductivity with flexible materials can greatly improve the conductivity and sensitivity of the flexible stretchable strain sensor while ensuring good flexibility.Some recent developments in film and fabric-based stretchable strain sensors made of different conductive materials were reviewed.
