Mimicking human’s tactile sensory capabilities enables the functionality of electronic skin (e-skin), which plays a crucial role in the interaction between humans and the environment, and operation life and stability are key factors for the application. Here, we present the development of passive e-skin with a layered structure to realize tactile capabilities. No external energy supply is required during the achievement of the tactile functions. The fabricated e-skin shows high sensitivity responses with pressure and temperature stimuli simultaneously. Discrimination of surface textures and mimicking humans’ thermosensation are demonstrated by the measurements of time-dependent voltage variations and theoretical fittings. The multifunctional tactile sensing e-skin with low energy consumption provides opportunities of flexible electronics in promising important applications in robotic skins, prosthetics, and wearable sensors.

具有高度灵敏触觉感知能力的无源电子皮肤

模仿人类的触觉感知能力使电子皮肤（e-skin）的功能成为可能，它在人与环境的交互中起着至关重要的作用，使用寿命和稳定性是应用的关键因素。在这里，我们展示了具有分层结构的被动电子皮肤的开发，以实现触觉功能。在实现触觉功能的过程中不需要外部能量供应。制造的电子皮肤同时显示出对压力和温度刺激的高灵敏度响应。通过测量随时间变化的电压变化和理论拟合来证明对表面纹理的区分和模仿人类的热感觉。
