| Abstract Scope |
Permittivity-based and inductance-based functionalities (different from conductivity-based functionalities) have been realized for 3D-printed polymer-based materials. Permittivity-based applications pertain to capacitors, as needed for electronic circuits, electrical energy storage, and sensors. Inductance-based applications pertain to inductors (needed for electronic circuits, transformers, electric generators, electric motors and magnetic energy storage) and sensors. Giant inductance has been discovered in structures based on polylactic acid (PLA), as derived from the microstructure and macrostructure of the material. For inductance, the material is electrically conductive, as rendered by the presence of a conductive filler in the PLA. The microstructure pertains to the arrangement of the filler and PLA molecules. The macrostructure pertains to the printed line direction relative to the electrical measurement direction. For permittivity, which relates to the capacitance, the material is not conductive, as provided by PLA without a filler. The capacitance and inductance also depend on the dimensions of the printed structure. |
