Specialty Macro Fiber Composites and Custom Designs
Smart Material also offers numerous specialized MFC layouts in addition to manufacturing Macro Fiber Composites in a wide variety of standard sizes. Specialty MFCs have more complex designs, including arrays of single MFCs, and also allow for electronic components to be integrated with the MFC.
This includes, for example, the Star MFC array for pumps and synthetic jets, the S1 and S2 types (which consist of sensor and actuator elements for a closed loop control), triangular-shaped MFCs for strain adaptation, and several other MFC arrays.We also offer MFCs integrated on various substrates, for example cantilever typ devices with the MFC being integrated with an FR4 PCB material.
A growing percentage of MFCs manufactured by Smart Material are customer specific designs. Typically the feasibility of customer specific applications are tested with the various standard MFC sizes first, including rapid prototyping. After the initial feasibility and prototyping phase, many of our customers will usually decide to make an application-specific custom design of the MFC. Some of the more common reasons for ordering a custom designed MFC are:
- to meet the exact required mechanical dimensions as well as strain and blocking force requirements,
- to combine several standard MFCs in one single array to save costs,
- to integrate electronic components, for example rectifiers for multi-MFC harvesters,
- to include specific power leads and connectors (to avoid standard cable connections).
