该通信描述了一种能够将美国手语（ASL）字母表无线翻译成可在计算机或智能手机上显示的文本的手套。该设备的关键部件是应变传感器，该传感器包括嵌入含氟弹性体中的碳颗粒压阻复合材料。这些传感器与可穿戴电子模块集成，该模块由数字化仪、微控制器和蓝牙无线电组成。有限元分析预测，当关节完全弯曲时，传感器上的峰值应变为5%。疲劳研究表明，即使在弯曲到最大程度1,000次时，传感器也能成功检测到指关节的关节。配合加速度计和压力传感器，手套能够翻译ASL字母表的所有26个字母。最后，从手套中获取的数据用于控制虚拟手;该应用程序提出了可伸缩和可穿戴电子产品可以使人类与虚拟环境交互的新方法。关键是，该系统由成本不到100美元的组件组成，不需要化学合成或进入洁净室。因此，它可以作为材料科学家评估新材料和柔性和可拉伸混合电子产品性能的测试平台。
This communication describes a glove capable of wirelessly translating the American Sign Language (ASL) alphabet into text displayable on a computer or smartphone. The key components of the device are strain sensors comprising a piezoresistive composite of carbon particles embedded in a fluoroelastomer. These sensors are integrated with a wearable electronic module consisting of digitizers, a microcontroller, and a Bluetooth radio. Finite-element analysis predicts a peak strain on the sensors of 5% when the knuckles are fully bent. Fatigue studies suggest that the sensors successfully detect the articulation of the knuckles even when bent to their maximal degree 1,000 times. In concert with an accelerometer and pressure sensors, the glove is able to translate all 26 letters of the ASL alphabet. Lastly, data taken from the glove are used to control a virtual hand; this application suggests new ways in which stretchable and wearable electronics can enable humans to interface with virtual environments. Critically, this system was constructed of components costing less than $100 and did not require chemical synthesis or access to a cleanroom. It can thus be used as a test bed for materials scientists to evaluate the performance of new materials and flexible and stretchable hybrid electronics.
