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 V. 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 h. 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.
触觉人机接口设备中的一个重大挑战是通过薄而柔软的贴片在低驱动电压下对人体皮肤进行无线机电刺激。在此，我们提出一种软触觉反馈系统，该系统使用具有环形凸起结构的高电荷聚合物驻极体薄膜，在5-20V的施加电压范围内在志愿者的指尖上诱发机械感觉。作为应用演示，一个3×3的致动器阵列用于传输图案化的触觉信息，如字母“T”“H”“U”和数字“0”“1”“2”。此外，与柔性锂电池和柔性电路板一起，构建了一个无束缚刺激贴片，可运行1小时。该分析模型、设计原理和性能表征可应用于其他可穿戴电子产品的集成，以实现其在增强现实（AR）、虚拟现实（VR）和机器人技术领域的实际应用。
