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: A rotational actuator includes a plurality of actuation beams each having an offset longitudinal axis with respect to one another; and a coupler connecting the plurality of actuation beams to one another, wherein the coupler is connected to each individual actuation beam at a position where connection of the coupler to other actuation beams causes the longitudinal axis of each actuation beam to be offset with respect to one another, wherein the plurality of actuation beams are lengthened or shortened to cause a moment about the coupler causing rotation of a point in the rotational actuator. The rotational actuator includes an amplification beam connected to the coupler such that the longitudinal axis of the amplification beam is substantially perpendicular to the longitudinal axes of the plurality of actuation beams. Additionally, the rotational actuator includes a resistant spring member connected to the amplification beam. The actuation beams can be thermally or piezoelectrically induced.
