BUSINESS Niche Market Piezo-composite materials: electrically inducing or detecting motion Piezo-electricity is the ability of some materials to generate an electric charge in response to applied mechanical stress, and then induce a voltage. In some cases, the potential difference can reach thousands of volts. The electric lighters on gas stoves are a common example. Conversely, when an electric field is applied, stress and strain appear within it. Lead zirconate titanate, Pb(Zr,Ti)O3, generally called PZT, is one of the most commonly used materials in this family. Smart Material develops and manufactures composites using this fibre-shaped oxide. Piezo-ceramic PZT fibres Piezo-ceramic PZT fibres are drawn using a textile spinning method which produces fibres with standard diameters of 105 µm, 250 µm and 800 µm and with typical lengths of 75 and 150 mm. few tenths of a millimetre. The actuators are contained in adaptive vibration control systems to eliminate unwanted vibrations in construction elements. This results in noise reduction, increased precision or higher loadbearing capacity. As the piezo effect is reversible, the fibre actuators can also simultaneously act as sensors or even harvest electrical energy from mechanical work. Applications range from vibration dampening in wings or car components to active forming of helicopter rotor blades, from exact positioning and stabilization of machine components to vibration damping in sports or household appliances, and from seismic disturbance measurements and health monitoring of buildings and aircraft to harvesting energy. The so-called 1-3 fibre composites are prepared by epoxy infiltration of fibre Focus Together with its investment partners, Volkswagen AG and SWAC Automation, and its research partners, the Fraunhofer Institute for Ceramic Technologies and Sintered Materials (IKTS) and NASA’s Langley Research Centre, Smart Material Corporation is developing and manufacturing innovative piezo-composite components for commercial applications in the industrial, defence, medical and consumer sectors. The company was founded in Sarasota, USA, in 2000. In July 2002, it founded Smart Material GmbH in Germany as a joint venture with Autovision GmbH (a 100% subsidiary of Volkswagen AG). Its main manufacturing facilities are located in Dresden, Germany, in the direct vicinity of the IKTS. bundles and dicing of the cube or cylinder-shaped blocks perpendicular to the direction of the fibres. The composite material shows superior ultrasound transduction properties due to its reduced acoustic impedance and high coupling factor. Piezo-composite materials Piezo-composite materials using these fibres combine the valuable piezoelectric properties of ceramics with the robustness and conformability of plastics. With the Macro Fibre Composites manufacturing technology, a NASA development, Smart Material possesses actuator know-how that has proved its suitability in aerospace applications and its versatility in many other applications. This technology makes it possible to assemble perfectly aligned fibre actuators that are no thicker than a The Macro Fibre Composites actuator More information: www.smart-material.com JEC Composites Magazine / No36 october - november 2007
