The overall goal of this program is to develop a gas compressor which uses modern piezoelectric or electrostrictive materials in place of a magnetic type motor, these materials can exert very large forces, but have only a limited travel. The key to the successful implementation of this compressor concept is a motion amplifier which will be studied at a CPI in a one cell simulator. Prior to building the simulator which will be used primarily to study material properties, we have analyzed the elastomer requirements. The motion amplifier is an elastomer which is squeezed between two plates. The elastomer is basically incompressible therefore, as the plates move together the elastomer will extrude from around the edges. Subcontracts were signed with CeramPhysics, Inc. and Pennsylvania State University in January. Penn State University, has been exploring tape casting of long narrow ribbons of PMNPT and PLZT type ceramic materials which wil serve as the drivers. CeramPhysics, compressor system and has completed a layout of a three cell simulator. APCI completed design and fabrication of a material testing device and has been getting dynamic property data on several different elastomers.
