One grand challenge in haptic human-machine interface devices is to electromechanically stimulate sensations on the human skin wirelessly by thin and soft patches under a low driving voltage. Here, we propose a soft haptics-feedback system using highly charged, polymeric electret films with an annulus-shape bump structure to induce mechanical sensations on the fingertip of volunteers under an applied voltage range of 5-20 Volts. As an application demonstration, a 3×3 actuators array is used for transmitting patterned haptic information, such as letters of ‘T’, ‘H’, ‘U’ letters and numbers of ‘0’,’1’,’2’. Moreover, together with flexible lithium batteries and a flexible circuit board, an untethered stimulation patch is constructed for operations of 1 hour. The analytical model, design principle, and performance characterizations can be applicable for the integration of other wearable electronics toward practical applications in the fields of AR (augmented reality), VR (virtual reality) and robotics.

用于人机界面触觉反馈的低压供电软机电刺激贴片

触觉人机界面设备的一大挑战是在低驱动电压下通过薄而柔软的贴片无线地机电刺激人体皮肤上的感觉。在这里，我们提出了一种软触觉反馈系统，该系统使用高度带电的聚合物驻极体薄膜，具有环形凸块结构，在 5-20 伏的施加电压范围内诱导志愿者指尖的机械感觉。作为应用演示，3×3 致动器阵列用于传输图案化的触觉信息，例如“T”、“H”、“U”字母和数字“0”、“1”、“2”。此外，结合柔性锂电池和柔性电路板，构建了一个不受限制的刺激贴片，可运行 1 小时。分析模型、设计原理、
