Charge-programmed three-dimensional printing for multi-material electronic devices

Three-dimensional (3D) printing can create complex geometries that could be of use in the development of electronics. However, the approach is mainly limited to non-functional structural materials, and the 3D printing of electronic devices typically requires multiple process stages of embedding, spraying and writing. Here, we report a 3D printing approach that can volumetrically deposit multiple functional materials within arbitrary 3D layouts...
