ElectroglaZ™- transparent power delivery

What is ElectroglaZ?

Zytronic’s ElectroglaZ technology is a bespoke lamination of non-conductive and conductive transparent glass. The arrangement allows power to be transferred across two or more individual layers within the laminate and tapped/extracted at the required locations to power multiple low power (<50V) devices. The delivery of this energy is wire/cable free and invisible to the user.

ElectroglaZ is a patent pending technology.

How Does ElectroglaZ Work?

To tap into the power, apertures (typically 30 to 100mm in diameter) are machined into the highly conductive glass where the required low power electrical devices will be fitted.  These devices connect to the positive and negatively charged inner coatings of the laminated glass. A 1mm wide printed conductive “busbar” around the perimeter of the conductive glass is applied to supply the external power into the laminate.

Unlike a traditional power deliver systems, electrical devices fitted into an ElectroglaZ do not require a wire or cable connection and appear to be freely ‘floating’ within an optically clear glass panel with no visual means of power connection.

How is ElectroglaZ Constructed?

  • In standard lamination arrangements ElectroglaZ panels are made of 2 or 4 layers of glass.
    • In a 2-layer arrangement (FIG 3.a) conductive layers face inwards and are separated by a lamination interlayer.
    • In a 4-layer arrangement (FIG 3 + 1.a), 2 x inner conductive layers are covered by 2 outer non-conductive laminated glass layers.FIG 2.
  • Power into the panel is delivered from the outer edge of the glass via a conductive printed busbar and extracted (power-out) from apertures located within the laminated panel.
  • Although powered devices are the primary focus, the technology also allows the transfer of data.
  • Apertures (holes in glass) can be at any location, or outline profile subject to certain design guidelines.
  • Glass can be processed in-house at Zytronic using a variety of methods i.e., cutting, machining, grinding, polishing, printing, thermal tempering and lamination.
