Research Topics


Phase I introduced a new concept of electronically integrated micro-drive actuator that addresses many army and commercial needs by driving at both higher strain and force than currently achievable. in a reversal of recent trends it introduced a low cost, higher performance system requiring low drive voltage levels and requiring small power (1/2W). Going beyond the Phase I SOW, EMF developed the first multifunctional integrated micro-actuator was designed, developed and fabricated as a demonstration that this technology is feasible. The project introduced many new, and patent applied for. innovations including inexpensive high performance flextensor actuator manufacture process and design. regenerative micro- drivers (amplifiers) for driving (piezo-) capacitive loads and multifunctional integrated actuators. The end product for Phase II shall be an advanced development prototype, packaged for field testing at Boeing ISDS, that addresses all deficiencies identified in Phase I. In particular, the project will address the issues of integrating (piezo-) power regulation, optimizing the mechanical design, developing a micro-drive actuator that incorporates a homogeneous fully protected housing. The design will be co-developed with Boeing ISDS Philadelphia. PA with the primary goal of mechanical FLIR isolation and ducted fan for the Comanche. BENEFITS: EMF has strategic partnerships with GTE Acoustics Corporation (turbine noise attenuation). Face International (geared towards Thunder process). American Piezo Ceramics, Ltd. and PRIMUS Technology Corporation to enable component and system level manufacture of Phase I/lI technology which will be available in standard & mil spec. format. Phase I microdriver production for commercial sale is already underway in a joint venture with PRIMUS.
