Tactile sensations are mainly transmitted to each other by physical touch. Wireless touch perception could be a revolution for us to interact with the world. Here, we report a wireless self-sensing and haptic-reproducing electronic skin (e-skin) to realize noncontact touch communications. A flexible self-sensing actuator was developed to provide an integrated function in both tactile sensing and haptic feedback. When this e-skin was dynamically pressed, the actuator generated an induced voltage as tactile information. Via wireless communication, another e-skin could receive this tactile data and run a synchronized haptic reproduction. Thus, touch could be wirelessly conveyed in bidirections between two users as a touch intercom. Furthermore, this e-skin could be connected with various smart devices to form a touch internet of things where one-to-one and one-to-multiple touch delivery could be realized. This wireless touch presents huge potentials in remote touch video, medical care/assistance, education, and many other applications.
触觉主要通过物理接触相互传递。无线触觉感知可能会引发我们与世界互动的一场革命。在这里，我们报告了一种无线自感知和触觉再现电子皮肤（e-skin），以实现非接触式触摸通信。我们开发了一种灵活的自感知执行器，以在触觉感应和触觉反馈中提供集成功能。当这种电子皮肤被动态按压时，执行器会产生感应电压作为触觉信息。通过无线通信，另一个 e-skin 可以接收此触觉数据并运行同步触觉再现。因此，触摸可以在两个用户之间以双向方式无线传输，形成触摸对讲机。此外，这种电子皮肤可以与各种智能设备连接，形成触摸物联网，实现一对一和一对多的触摸传递。这种无线触摸在远程触摸视频、医疗保健/辅助、教育和许多其他应用中具有巨大的潜力。
