Abstract

Smart gloves with their multifunctional sensing capabilities, hold a promising in human-machine interface (HMI) applications. In this work, we present a smart glove based on single-walled carbon nanotubes (SWCNTs) incorporated within a polydimethylsiloxane (PDMS) matrix integrated flexible strain sensor. The flexible strain sensor is designed and fabricated to serve as a crucial sensing component for the smart glove. The integration of SWCNTs with PDMS offers a unique combination of mechanical flexibility and electrical sensitivity, making it an ideal candidate for real-time monitoring and feedback in HMI applications. The fabricated SWCNTs/PDMS strain exhibits a high sensing range, covering up to a strain range of 70%, along with high sensitivity, characterized by a gauge factor (GF) of 73. Additionally, the strain sensor demonstrates excellent linearity, reliability, and durability, enduring repeated loading and unloading for 3000 cycles under a 50% strain. Furthermore, the developed smart glove successfully extends sensing functionality, enabling real time-tasks such as finger motion detection, controlling robotic fingers and can be used in the field of smart wearable electronics and HMI applications.

用于人机界面应用的SWCNTs/PDMS复合应变传感器集成智能手套的开发

智能手套具有多功能传感能力，在人机界面（HMI）应用中具有广阔的前景。在这项工作中，我们提出了一种基于单壁碳纳米管（SWCNTs）的智能手套，该手套结合了聚二甲基硅氧烷（PDMS）矩阵集成柔性应变传感器。柔性应变传感器是为智能手套的关键传感元件而设计和制造的。SWCNTs与PDMS的集成提供了机械灵活性和电灵敏度的独特组合，使其成为HMI应用中实时监测和反馈的理想选择。制备的SWCNTs/PDMS应变具有高传感范围，可覆盖高达70%的应变范围，同时具有高灵敏度，其测量因子（GF）为73。此外，该应变传感器具有出色的线性度、可靠性和耐用性，可在50%应变下重复加载和卸载3000次。此外，开发的智能手套成功扩展了传感功能，实现了手指运动检测，控制机器人手指等实时任务，可用于智能可穿戴电子产品和HMI应用领域。
