Abstract: 3D printable inks are disclosed which include one-part room temperature vulcanized (RTV) silicone and carbon particles such as carbon nanotubes (CNTs). Butyl acetate may be used as a solvent to disperse the CNTs in the silicone in the ink precursor. The one-part nature of the inks (i) enables to print without prior mixing and cures under ambient conditions; (ii) allows directly dispensing 100 ?m resolution printability on nonpolar and polar substrates; and (iii) forms both self-supporting and high-aspect-ratio structures, key aspects in additive biomanufacturing that eliminate the need for sacrificial layers; and (iv) lends efficient, reproducible, and highly sensitive responses to various tensile and compressive stimuli.

Abstract: Functionalized microscale 3D devices and methods of making the same. The 3D microdevice can be realized with the combination of top-down (lithographic) and bottom-up (origami-inspired self-assembly) processes. The origami-inspired self-assembly approach combined with a top-down process can realize 3D microscale polyhedral structures with metal/semiconductor materials patterned on dielectric materials. In some embodiments, the functionalized 3D microdevices include resonator-based passive sensors, i.e. split ring resonators (SRRs), on 3D, transparent, free-standing, dielectric media (Al2O3).

Abstract: Methods of making a microscale, free-standing, 3D, polyhedral, hollow, GO (or other graphene-based) structure using an origami-like self-folding approach. The origami-like self-folding process allows for easy control of size, shape, and thickness of graphene-based membranes, which, in turn, permits fabrication of freestanding 3D microscale polyhedral GO structures for example. With the 3D GO, a novel optical switching behavior is created, resulting from a combination of the geometrical effect of the 3D hollow structure and the water-permeable multi-layered GO membrane that affect the optical paths.
