Actuation

Macro Fibre Composite actuator

The Macro Fiber Composite (MFC) is an innovative actuator that offers high performance and flexibility in a cost-competitive device. The MFC consists of rectangular piezo ceramic rods sandwiched between layers of adhesive and electroded polyimide film.

This film contains interdigitated electrodes that transfer the applied voltage directly to and from the ribbon shaped rods. This assembly enables in-plane poling, actuation, and sensing in a sealed, durable, ready-to-use package. When embedded in a surface or attached to flexible structures, the MFC actuator provides distributed solid-state deflection and vibration control.

Benefits:

  • Flexible and durable
  • Increased strain actuator efficiency
  • Directional actuation/sensing
  • Damage tolerant
  • Conforms to surfaces
  • Readily embeddable
  • Environmentally sealed package
  • Demonstrated performance
Micro Fibre Composite

Applications for the MFC range from vibration reduction to shape-changing structures, from micropositioning to dynamic structural health monitoring or force-sensor applications.

Product displayed is manufactured by Smart Material Corp. under license agreements of the National Aeronautics and Space Administration (NASA). If sold in the U.S.A. only for sale for U.S. government funded projects and procurements. No restrictions in all other countries, except where prohibited by the US government.

Active Damping Device

The Active Damping Device (ADD) consists of a vibration sensor, an inertial actuator and a controller. The ADD introduces structural damping into any vibration mode that can be observed by the sensor.

The ADD is not sensitive to changes in the supporting structure dynamics; frequency variation of 100% have been observed without performances degradation.

The simple and compact design provides:

Active Damping Device
  • Stand-alone device
  • Wide-band structural damping
  • Insensitive to structural uncertainty
  • Simple implementation (non intrusive)

Now available in 1N, 45N and 1kN sizes to meet your different application requirements.
