MFC P2 type - PEH, Piezo Electric Harvester Patches
The P2 type MacroFiberComposites™ (MFCs) are especially designed for energy harvesting applications. The P2 type MFCs feature a high electric source capacitance and increased electric charge generation. The MFCs are based on piezo electric fibers and are environmentally sealed, which yields increased flexibility and robustness compared with standard, monolithic piezo ceramic harvesters.
Due to the piezo fiber design of the P2 type MFCs, the MFC piezo harvester has a preferred direction for coupling strain into the device for energy generation. The preferred strain direction
(compression) is parallel to the fiber axis. The fiber axis is parallel to the length of the respective MFC model, as listed in the table below.
Please note: All below listed MFCs are shipped not attached to any structure for proper strain coupling. In order to generate energy from strain the MFC
needs to be bonded to a material of your choice. Please check out our FAQs, Tutorial or Technote section for proper bonding instruction.

MFC-P2 cantilever type PEH
The MFC-P2 cantilever PEHs allow for energy harvesting from bending motions & vibrations. The MFC cantilevers are comprised of a glass fiber composite (FR4) as the base material with an integrated P2 type MFC.
