A stereoscopic endoscope employing a single light sensor array and a lenticular lens layer located at a proximal end of the endoscope, a pair of periscopic prisms located at a distal end of the endoscope and an optical relay assembly array located between the pair of periscopic prisms and the light sensor array. A fluid amplifier includes a housing assembly, a piezo-electric element, two amplification stages, and a rod. In one embodiment, the insulating microwave packaging material is formed by bonding a microwave interactive material substrate that creates sensible heat upon exposure to microwave energy to a second substrate along bond lines arranged in a pattern to form closed cells.
