由于柔性和可穿戴电子设备与人体的轻松交互，对它们的需求正在增加。柔性、可拉伸和可穿戴的传感器可以很容易地安装在衣服上或直接附着在身体上。特别是，高度可拉伸和敏感的应变传感器需要用于人体运动检测。在这里，我们报告了基于银纳米线（AgNW）网络和PDMS弹性体的纳米复合材料的高度柔性、可拉伸和敏感的应变传感器，该纳米复合材料呈三明治结构的形式（即，AgNW薄膜嵌入两层PDMS之间）。基于AgNW网络-弹性体纳米复合材料的应变传感器显示出强大的压阻性，计量因子在2至14范围内可调，并且具有高达70%的高拉伸性。我们证明了我们的高性能应变传感器的适用性，通过制作一个手套集成了五个应变传感器的手指的运动检测和虚拟环境中的化身的控制。
The demand for flexible and wearable electronic devices is increasing due to their facile interaction with human body. Flexible, stretchable and wearable sensors can be easily mounted on clothing or directly attached onto the body. Especially, highly stretchable and sensitive strain sensors are needed for the human motion detection. Here, we report highly flexible, stretchable and sensitive strain sensors based on the nanocomposite of silver nanowire (AgNW) network and PDMS elastomer in the form of the sandwich structure (i.e., AgNW thin film embedded between two layers of PDMS). The AgNW network-elastomer nanocomposite based strain sensors show strong piezoresistivity with tunable gauge factors in the ranges of 2 to 14 and a high stretchability up to 70%. We demonstrate the applicability of our high performance strain sensors by fabricating a glove Integrated with five strain sensors for the motion detection of fingers and control of an avatar in the virtual environment.
