Abstract: Embodiments of energetic devices are provided herein. In some embodiments, an energetic device may include a substrate having a plurality of pores formed in a portion of the substrate; a plurality of carbon nanotubes disposed proximate the plurality of pores such that a reaction within one of the plurality of pores or the plurality of carbon nanotubes initiates a reaction within the other of the plurality of pores or the plurality of carbon nanotubes; a solid oxidizer disposed in the plurality of pores and the carbon nanotubes; and an initiator to initiate a reaction within one of the plurality of pores or the plurality of carbon nanotubes.

Abstract: According to embodiments, an optically-actuated mechanical device comprises at least one deformable section formed of: an element including an intrinsic stress differential or gradient, the stress tending to urge deformation of one portion relative to another portion; and an optically-sensitive material which is configured to (i) initially prevent deformation of the device, and (ii) upon sufficient heating by absorbing optical energy allows the element to deform. The devices may be incorporated into various devices and apparatuses for select, non-contact actuation using only optical energy, for example, via light, from one or more lasers. Methods for fabricating and actuating such devices are also disclosed.
