ABSTRACT:
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.
