Flexible conformal electronics can be applied in many novel fields, such as wearable sensors, curved display and epidermal electronics, owing to their good adaptability to curved surfaces. Currently, the manufacturability of flexible electronics has been greatly enhanced with the development of various printing technologies. In this paper, the active conformal deformation model and device are presented under the framework of transfer printing. In particular, we present a practical deformation process of a multi-fingered actuator based on the minimization of elastic potential energy of the flexible membrane. The whole transfer printing platform as well as the multi-fingered manipulator are manufactured and the feasibility of them are verified with multiple tests on different target surfaces.

柔性共形电子器件由于其对曲面的良好适应性，因此可应用于许多新领域，例如可穿戴传感器，曲面显示器和表皮电子器件。当前，随着各种印刷技术的发展，柔性电子设备的可制造性已经大大提高。在转移印刷的框架下，提出了主动保形变形模型和装置。特别地，我们基于柔性膜的弹性势能的最小化提出了多指致动器的实际变形过程。制造了整个转移印刷平台以及多指机械手，并通过在不同目标表面上进行多次测试验证了它们的可行性。
