Abstract: A foam ink composition for printing porous structures comprises stabilizing particles and gas bubbles dispersed in a solvent. The stabilizing particles comprise a predetermined interfacial energy so as to exhibit a contact angle with the solvent of from about 15° to about 90°. At least a portion of the stabilizing particles are positioned at interfacial regions between the solvent and the gas bubbles, thereby stabilizing the gas bubbles in the foam ink composition. A 3D printed hierarchical porous structure comprises one or more continuous filaments arranged in a predetermined pattern on a substrate, the one or more continuous filaments comprising a sintered material and including a porosity of at least about 40 vol. %.

Abstract: A printed stretchable strain sensor comprises a seamless elastomeric body and a strain-sensitive conductive structure embedded in the seamless elastomeric body. The strain-sensitive conductive structure comprises one or more conductive filaments arranged in a continuous pattern. A method of printing a stretchable strain sensor comprises depositing one or more conductive filaments in a predetermined continuous pattern into or onto a support matrix. After the depositing, the support matrix is cured to embed a strain-sensitive conductive structure in a seamless elastomeric body.
