First results of the FP7 project MATFLEXEND will be presented. In contrast to electrostatic MEMS based parallel plate transducers or dielectric elastomer systems here, the capacitance is varied as function of the mechanical load with help of liquid metal or electrically conducting elastomers. These flexible energy harvesters are especially intended for wearables including smart textiles, shoes and other applications where mechanical compliance is needed.
Numerical simulation was used to identify the influence of material parameters and parasitic circuit elements on the harvester performance as function of actuation frequency. First experimental results are shown and the behaviour of liquid metal and elastomer electrodes in combination with several high-k dielectrics is discussed.
