Definitions

  • the present invention relates to a protection device capable of solving a particular type of pollution such as electrical and magnetic pollution.
  • Electromagnetic pollution is currently a widespread problem; all structures, devices, lines through which electric current flows generate electromagnetic fields; moreover, the waves of radio, television, telephone and cellular phone systems add waves of all kinds.
  • Electrosmog (this is the term used to designate electromagnetic pollution) interferes with and alters biological waves, the microinf ormation of living matter, to the point that once correction and repair systems have been saturated, dysfunction and disease arise.
  • an iron generates 30 uT
  • a blender generates 700 uT
  • a television set generates 500 uT
  • an electric shaver generates 1500 uT
  • a hair dryer generates 2500 uT; in some work environments (welding machines, induction furnace, amplifiers, transformers) the strength is 1000 uT.
  • the natural electrical field has an intensity (strength) of 0.0001 V/m, in comparison with
  • Bioarchitecture is currently very active in attempting to make domestic and work environments healthier and more livable; without delving into detail, which would make us stray off topic, suffice it to mention that the proposed solutions are very modest, complicated and often unfeasible. For example, to prevent the fields generated by electric current in the wires of a house, these wires would have to be shielded or it would be necessary to place a breaker (inactivate them), but even so, all the other sources of pollution remain.
  • the aim of the present invention is to provide a protection device adapted to reduce the problem of electromagnetic pollution in home and work spaces, in offices and more generally in the construction sector, to the point of fully eradicating it for certain types of electrosmog.
  • Figure 1 is a schematic perspective view of the device according to the present invention.
  • Figure 2 is a schematic perspective view of a possible connection made of two devices according to the present invention.
  • the device according to the invention consists of a protection device which, in a particular embodiment, is constituted by a membrane 10 coupled to an electromagnetic radiation blocking/absorbing layer such as an earthed shielding mesh 2.
  • the membrane is constituted by a matrix 1 which is suitable to act as a substrate for the mesh 2, such as for example a permeable, semipermeable or impermeable plastic polymer.
  • the mesh 2 is preferably made of thin conducting metal wire, such as for example copper.
  • the device can be constituted by the combination of a supporting substrate and of carbon and/or graphite and/or propolis parts.
  • the membrane 10 can be independent, as described above, or can be integrated in existing membranes, such as those used for insulating and non-insulating coverings, among which bitumen-polymer membranes are widely used. In the latter case, i.e., in association with an existing product, said product will undergo constructive modifications which are suitable to integrate the metal mesh, since the supporting matrix 1 is already available within the membrane itself.
  • the impermeabilizing mass of bitumen polymer can have the metal mesh 2 embedded therein or associated therewith.
  • the device of the invention is to be used on the largest possible number of walls, be they perimetric outer walls or internal partitions.
  • This produces a shielding effect, similar to a Faraday cage, which is capable of neutralizing most of the electromagnetic radiation originating from outside the enclosed spaces, such as high frequencies and low frequencies (microwaves, radar, satellites, mobile telephones, television sets, radio waves, electrical installations) and is capable of absorbing and blocking the passage through walls or partitions (wave breakers) of radiation from inside the enclosed spaces, such as the radiation emitted by electrical systems and electrical household appliances.

  • the device of the invention must comply with a small number of simple but important refinements: the first one is to electrically connect the metal meshes 2 of the various membranes 10 to each other (as shown in Figure 2); the second one is to connect them to an electrical earthing point.
  • this becomes easy, since the covering membranes are inherently mutually associated without discontinuities and it is therefore sufficient to provide, in finishing the membranes, exposed • portions of the metal mesh 2 at their edges, so that during installation the metal parts make contact with each other and with one or more earthing wires 6 (see Figure 2).
  • the membrane 10 of course has different structures and models according to the different intentions and possibilities of application.
  • the model associated with bitumen-polymer membranes used for insulation and external coverings has been described above.
  • Perimetric walls might use membranes with surfaces which are suitable to grip the plaster or other types of mortar or paint according to the finishing technique.
  • Internal partitions might use the same membranes as the external walls, which might be semi-permeable or impermeable, or more suitable permeable membranes.
  • permeable membranes it is sufficient to form the matrix 1 in a fabric-like form, or as a porous film, or to use currently commercially available technological materials which allow moisture to pass (vapor-permeable) and repel water.
  • said membranes 10 can be coupled to other materials, such as wood, plastics, etcetera in order to form shielded furniture and appliances.
  • the flap 3 of one membrane 10 is made to overlap the flap 4 of an adjacent membrane, by torching or gluing or punching, so that the two metal meshes 2 touch each other.
  • metallic filaments are present which are arranged so as to divide the surface into sub-portions having progressively smaller areas, such as for example along parallel lines. The purpose and operation are in any case the same: to trap the largest possible number of electric and magnetic waves, so as to block electromagnetic fields, discharging them by earthing.
  • the materials that constitute the membrane 10 have a low cost in terms of essential components, i.e., the conducting metal and the supporting matrix, which can also be obtained with waste material and recycled material such as plastics and the like, said membrane can be expected to become widely used, particularly in view of its advantages regarding health, which is receiving increasing consideration.
  • the electro-ecological model instead of ordinary bitumen-polymer membranes for coverings: price and (if one wishes) installation have the same cost but offer entirely different advantages.
  • External containment enclosures of all electrical appliances such as refrigerators, television sets, ovens, monitors, washing machines: internal application of the membrane where possible.
