Electronic skin (e‐skin) has attracted extensive attention owing to its potential application in biomedical sensors, intelligent robots, and bionic prostheses. To imitate better or even surmount the perceptive capabilities of human skin, multifunctional e‐skin is an important trend in the field. A novel stable perovskite intermediate gel (PIGel) is obtained during the MA2SnI6 perovskite crystallization process. This Sn‐based PIGel exhibits good conductivity and outstanding wettability on different polymer substrates. Based on these properties, it is successfully applied to the field of e‐skin. Flexible and stretchable multifunctional e‐skin sensors are developed based on it. Stretching, finger bending, voice recognition, pulse monitoring, temperature, and electricity response are achieved in one e‐skin device. In addition, the MA2SnI6 perovskite single crystal is prepared by solvent engineering. The formation mechanism of the PIGel and MA2SnI6 single crystal is studied in detail. This work broadens the selection range of sensing materials for e‐skin and paves the way to achieve multifunctional sensors with the facile fabrication process.

基于钙钛矿中间凝胶的多功能电子皮肤
电子皮肤（e-skin）由于其在生物医学传感器，智能机器人和仿生假肢中的潜在应用而受到广泛关注。为了更好地模仿甚至超越人类皮肤的感知能力，多功能电子皮肤是该领域的重要趋势。在MA 2 SnI 6期间获得了新型的稳定的钙钛矿中间凝胶（PIGel）钙钛矿结晶过程。这种基于Sn的PIGel在不同的聚合物基材上显示出良好的导电性和出色的润湿性。基于这些特性，它已成功应用于电子皮肤领域。在此基础上开发了可伸缩的多功能电子皮肤传感器。在一台电子皮肤设备中可以实现伸展，手指弯曲，语音识别，脉冲监测，温度和电响应。另外，MA 2 SnI 6钙钛矿单晶是通过溶剂工程制备的。PIGel与MA 2 SnI 6的形成机理对单晶进行了详细研究。这项工作拓宽了用于电子皮肤的传感材料的选择范围，并为通过便捷的制造工艺实现多功能传感器铺平了道路。
