Abstract: An in-situ poled ferroelectric prints with true 3D geometry is provided with an intercalated electrode design where soft polymer matrixes are selected for the ferroelectric layers, and rigid polymer matrixes are selected for the electrode layers, thus mimicking nacre architecture with a ceramic-like piezoelectric property and bone-like fracture toughness. Lithium-doped potassium sodium niobite (Li—KNN) microparticles may be used to produce ferroelectric properties and to create strong interfacial bonding with the interfacing electrode layers. Polylactic acid (PLA) in the electrode layers may be used to facilitate strong interfacial bonding with the Li—KNN microparticles.

Abstract: A wearable medical bandage is provided having an energy harvesting generator that harvests mechanical energy from the user's natural body and muscle motions to produce electrical energy. The electrical energy induces an electric potential across the wound opening producing accelerated skin wound recovery under the voltage fluctuations produced by the power generator.

Abstract: An energy harvesting system for use with the human body may use an eccentrically mounted weight winding a mainspring that drives a mechanical clock mechanism. The mechanical clock mechanism in turn may produce pulses of electricity, for example, through periodic flexing of a piezoelectric or triboelectric material during the regular motion of the mechanical timing mechanism. By remaining in a mechanical rather than electrical domain, improved simplicity and efficiency may be obtained in the generation of regularly spaced uniform pulses.
