Developing a Wearable Multifunctional Composite Component
This paper focuses on the design and development of a low-cost multifunctional composite component integrated into a shoe hill that generates power in the order of milliwats (mW) through piezoceramic (PZT) stacks and stores this harvested energy in a capacitor integrated into the composite.The use of a thin-film lithium battery integrated into the composite is also explored as a means of permanent power storage.PZT bimorph elements are stacked in a cantilever manner.The space in-between and around the elements is being filled with foam,which provides structural support as well as walking comfort.An insole composite with a PZT layer is also developed that is capable of producing 2.2roW of power to give a total power output of 12.2mW for the in-heel insole combination.The experimental results revealed that the use of PZT bimorph elements (d33=110) instead of polyvinylidene difluoride PVDF sheets (d33=20) increased the power generation potential over five folds,which is further compounded by stacking the PZT elements.
