The following component describes a cell layer made of piezoelements and nano-generators,
Which together form a complete module. The main structure consists of a clear acrylic glass plate,
Which serves both as a protective layer and as a support material for the attached piezoelements
And nano-generators. The acrylic glass plate measures 598 millimeters in length, 398 millimeters
In width, and has a thickness of 2 millimeters. The nano-generators and piezoelements are
Strategically arranged on this plate.
Directly on the acrylic glass plate, the piezoelements and the nano-generators-U (the lower parts
Of the nano-generators) are mounted on the same level. Above the piezoelements and the nanogenerators-U, there is a PTFE film. This film, which also measures 598 mm X 398 mm, protects the
System from water and other weather influences.
The piezoelements are circular, and there are 504 of them on the acrylic glass plate. Each of these
Piezoelements has a diameter of 15 mm. They are arranged in a checkerboard or matrix pattern:
28 piezoelements are placed along the longer side of the plate, and 18 along the shorter side,
Resulting in a total of 504. There is a uniform spacing of 5 mm between the piezoelements, and
They maintain an even distance of 21.5 millimeters from each edge of the acrylic glass plate. This
Arrangement ensures that the piezoelements utilize as much area as possible without interfering
With each other.
The total area covered by the piezoelements is 89, 019 mm². Each piezoelement has two wires_
One positive and one negative. These wires are routed downwards through specially designed
Holes in the acrylic glass plate. The holes have a diameter of 5 mm and run vertically through the
Plate, allowing the wires to be connected underneath the plate. To ensure that no moisture
Penetrates the system, the holes are sealed with a special adhesive after the module is
Assembled.
The nano-generators consist of two cross-shaped parts, the nano-O (upper part) and the nano-U
(lower part). The nano-U part is mounted directly on the acrylic glass plate between the
Piezoelements, while the nano-O part sits directly above the nano-U part on the PTFE film. The
Two parts are separated only by the PTFE film and are perfectly aligned on top of each other.
The cross-shaped nano parts are made of thin aluminum strips, as aluminum is an ideal material
For utilizing the triboelectric effect. A nano-cross has four arms, each 7 millimeters long and 4
Millimeters wide, resulting in a total length of 18 millimeters for the entire cross.
Now, let's examine the component of a single nano-generator within the module: The nano-O
Cross is in contact with a black positive wire. The nano-U cross is in contact with a red negative
Wire. Thus, each nano-generator consists of two wires (positive and negative), which, like the
Piezoelements, are routed downwards through holes in the acrylic glass plate. These holes are
Slightly offset to ensure that the wires do not touch and that there is no short-circuit situation.
The wires are then connected underneath the acrylic glass plate to allow for a clean current flow.
Again, the holes are sealed with a special adhesive after completion to protect the system from
Water and other environmental influences.
