Embodiment Construction

[0045] Hereinafter, the present invention will be described in more detail in exemplary embodiments by referring to the accompanying drawings.

[0046] The present invention is based on the concept that an increase in tension in a free-standing section of a membrane comprising a HARM structure can be archived by passing an electric current through the free-standing section of the membrane. According to Ampere's law, the attractive force of the magnetic field formed between two substantially parallel current-carrying HARM structures arises. When two HARM structures carrying current in the same direction are placed in each other's magnetic fields, they can physically attract each other if the current is sufficient. The current passing through the network of parallel HARM structures is split up between individual paths, so the current passing through a single (individual) HARM structure depends on the number or membrane of said HARM structures Density. Since it may not be feasi...

Abstract

An apparatus, comprising a film (103) comprising a network of conductive and / or semi-conductive high aspect ratio molecular structures is presented. The apparatus also comprises a frame (102) arrangedto support the film (103) at least at least two support positions so that a free-standing region (101) of the film (103) extends between the at least two support positions. The two or more electricalcontact areas electrically coupled to the film (103), and these electrical contact areas are arranged to pass electric charge across the free- standing region (101) of the film (103) at a current between 0.01 and 10 amperes.

Description

technical field [0001] The present invention relates to thin film technology. In particular, the present invention relates to apparatuses (devices) comprising films with high aspect ratio molecular structures. Background technique [0002] High-aspect-ratio molecular structures (HARM structures), such as carbon nanotubes (CNTs) or other nanoscale structures with high aspect ratios, possess unique electrical, optical, thermal, and mechanical properties, which make them promising candidates for many applications. s material. [0003] Membranes including the high aspect ratio molecular (HARM) structures described above may include standalone or free-standing (self-supporting) parts useful for various applications. The free-standing portion of the membrane is sensitive to fluctuations in air pressure or thermal radiation pressure. Under such pressure, the membrane may rupture and lose its function. Additionally, after prolonged use, the web of free-standing HARM structures t...
