Layered Composite with Non-Continuous Openings, Method for Production, and Structural Element Therewith

Simple SummaryContent extracted from patent full text and abstract with AI.

This invention describes a layered composite material (Schichtenverbund) with a porous substrate that includes both impermeable openings and permeable pores. These pores are sealed on one side with an electrically insulating, flexible, and elastic cover layer of nanometer thickness, made from materials such as polymers, oxides, gels, or biological membranes. This substrate is useful in electronic components that generate periodic pulses even when a constant DC voltage is applied.

Patent Abstract

The porous substrate useful in electronic component for generating periodic pulsation under constant DC voltage, comprises impermeable openings (NDG) and permeable pores (PO) that are locked at a side of the substrate with an electrically isolating, flexible and elastic non- porous cover layer (DS) of constant thickness (delta ) in nm-range. The cover layer covers the total substrate in panel form or individual permeable pores in membrane form. The cover layer is made of polymer, oxide, gel or biological membrane.

The cover layer covers the total substrate in panel form or individual permeable pores in membrane form. The cover layer is made of polymer, oxide, gel or biological membrane. Corroded ion traces are formed as a pore in an electrically isolating foil as substrate. The foil is made of polymer, silica or mica. Independent claims are included for: (1) procedure for manufacturing porous substrate with impermeable openings; and (2) electronic component for generating periodic pulsation under constant direct current voltage.
