An approach to precision additive fabrication uses jetting of cationic compositions in conjunction with a non-contact (e.g., optical) feedback approach. By not requiring contact to control the surface geometry of the object being manufactured, the approach is tolerant of the relative slow curing of the cationic composition, while maintaining the benefit of control of the deposition processes according to feedback during the fabrication processes. This approach provides a way to manufacture precision objects and benefit from material properties of the fabricated objects, for example, with isotropic properties, which may be at least partially a result of the slow curing, and flexible structures, which may not be attainable using conventional jetted acrylates.

The present invention relates to an elastic conductor with high conductivity and stable electrical performance under stretching. The elastic conductor comprises a matrix material; a plurality of electrically conductive structures embedded in the matrix; and one or more particles embedded in the matrix, wherein the particles are configured to release an electrically conductive material upon stretching of the elastic conductor. In a preferred embodiment, each of the particles comprises a core of the electrically conducting material, such as liquid eutectic gallium indium alloy, and an outer shell surrounding the core, such as gallium oxide.
