A versatile cavity actuator. The versatile cavity actuator includes a cavity having one or more polymer-based sidewalls. An energetic material is disposed therein. A heater is disposed on or within the cavity. In a specific embodiment, the cavity includes a thermally insulating base positioned beneath the heater, which is positioned near the bottom of the cavity. The polymer-based sidewalls are constructed from a photo-curable epoxy, which is disposed on a substrate via microelectromechanical processes. The sidewalls are angled or parabolic and are constructed via a low-temperature lithographic spin process compatible with post integrated circuit processing.

For the purposes of the present discussion, a microcavity actuator is any miniature cavity actuator, such as an initiator or thruster. For example, cavity initiators with dimensions on the order of nanometers or millimeters are also microcavity actuators. Cavity actuators are often called Electro-Explosive Devices (EED's).
