Electronic skin (E‐skin) imitates human skin by converting external stimuli into electrical signals. E‐skin requires high flexibility and a high level of device integration. Unlike conventional E‐skin creation methods, a highly sensitive pressure sensor matrix (100 pixels cm⁻²) made of position‐registered elastic conductive microparticles (MPs) is created. The MPs form a Schottky junction with the bottom electrode and the current through the junction is sensitive to external pressure, forming a simple one‐selector two‐terminal device array. The Schottky junction eliminates the electrical cross talks between the sensor pixels consisting of 64 MPs in each. The flexible pressure sensor matrix is used as an artificial fingertip for Braille reading and as an electronic scale based on detailed force distribution. This work opens up the possibility that assembled MPs, which have been a long‐standing research topic in academia, can be used to make practical electronic devices.

电子皮肤触觉传感器矩阵，由位置记录的导电微粒像素化，创建压力敏感选择器

电子皮肤（E皮肤）通过将外部刺激转换为电信号来模仿人类皮肤。电子皮肤需要高度的灵活性和高度的设备集成度。与传统的电子皮肤创建方法不同，高度敏感的压力传感器矩阵（100像素cm ^-2）由位置注册的弹性导电微粒（MPs）制成。MP与底部电极形成一个肖特基结，流经该结的电流对外部压力敏感，从而形成一个简单的一选二端器件阵列。肖特基结消除了每个像素由64个MP组成的传感器像素之间的电气串扰。柔性压力传感器矩阵可用作盲文阅读的人工指尖，也可用作基于详细力分布的电子秤。这项工作为在学术界长期研究的组装式MP可以用于制造实用的电子设备开辟了可能性。
