Figure 7 also illustrates schematically how the capture element 100, in an area close to its base or in its base, comprises an elastic core 1 13 surrounded by piezoelectric material 1 1 1. In some embodiments of the invention, said first repetitive movement of at least part of said capture element is arranged to trigger said oscillation by displacement followed by release of a moveable portion of said at least one generator piezoelectric element, such as by deforming said generator piezoelectric element by displacing part of it, for example, by bending or otherwise deforming it. In some embodiments of the invention, the displacement is caused by contactless means, thereby reducing the risk for wear. Figures 1 -3 reflect schematically some aspects of a possible embodiment of the invention, and that said embodiment of the invention has in common with the aerogenerator described in WO-2012/017106-A1. Figure 8 is a diagram of part of the control sub-system of a generator according to a possible embodiment of the invention.

Fusion 360 Joints and Motion Links - YouTube - Fusion Consequently, and due to the intrinsic characteristics of the piezoelectric elements, during the deformation from the first configuration to the second configuration, the energy that the capture element transfers to the piezoelectric element transforms into very little electrical energy, and is for the most part accumulated in the generator piezoelectric element in the form of elastic potential energy.

Therefore, and due to the intrinsic characteristics of the piezoelectric elements, during the deformation from the first configuration to the second configuration, the energy that the capture element transfers to the piezoelectric element is converted into very little electrical energy, and is for the most part accumulated in the generator piezoelectric element in the form of elastic potential energy.

In this aspect of the invention, the generator comprises at least one first magnet associated to the moveable element in such a way that the first magnet is moved according to the movement of said moveable element, and at least one second magnet associated to said, at least one, generator piezoelectric element in such a way that a movement of the second magnet produces a deformation of the generator piezoelectric element. The capture element is anchored to the base 100, and this anchoring is reinforced by anchoring member 106. Also in this embodimient, the lower part 100B of the capture element features an elastic core 1 13. In the illustrated embodiment, the free upper ends of the generator piezoelectric elements are curved, with a radius of curvature that increases with height (that is, the ones at a higher level, such as 2H, feature a larger radius of curvature than those at a lower level, such as 2E, in accordance with the radius of curvature of the path followed by the capture element at the corresponding level.

Dolores lumbares por levantar mucho peso - Eres deportista The use of piezoelectric material is mentioned in relation to the adjustment of a support arm, used to support a spherical bluff body, and in relation to an electromechanical support arm employing a material such as a piezoelectric polymer which converts mechanical deformation into electricity. In this way, an oscillating movement of the first magnet 1 1 to one side and the other, with the frequency at which the capture element 100 oscillates, can give rise to an oscillation of the generator piezoelectric element 1 at a much higher frequency, increasing the efficiency of the conversion from mechanical energy into electrical energy, and without having to resort to complex multiplier mechanisms, etc. US-2008/048455-A1 relates a system including a bluff body adapted to interact with a fluid to generate a series of von Karman Vortex oscillating pressure gradients so as to convert part of the energy of the fluid into mechanical motion of the bluff body.

The motion of the bluff body is converted into electrical energy. This can be done by acting on one or more piezoelectric elements associated to the capture element, for example, by acting on said part of piezoelectric material. For this reason, their performance is affected by the working electrical voltage at which they are made to function. In some embodiments of the invention said, at least one, generator piezoelectric element has a substantially flat configuration, and one side fixed to a base, leaving the other side free. In some embodiments of the invention, a capture element is used having a height of between 1 metre and 300 metres, or more, and having a natural oscillation frequency of between 0.01 Hz and 20 Hz, such as between 0.01 Hz and 3 Hz. In some embodiments of the invention, the capture element, or at least the upper and/or major part thereof, is, at least to a substantial extent, made of materials that include fibreglass and/or epoxy resin and/or polyester resin and/or polyamide resin.

In some embodiments of the invention, the capture element includes at least a first part (such as an upper part) and a second part (such as a lower part), said first part being arranged so that said lift force acts on said first part, said second part being more flexible and/or more elastic than said first part and being arranged to connect said first part to a base, so that when said lift force acts on said capture element, said capture element sways with regard to said base. In some embodiments of the invention, the displacement is caused by magnetic means, such as by repulsion between magnets. In some embodiments of the invention, a plurality of the generator piezoelectric elements are arranged on a first support and another plurality of the generator electric elements are arranged on a second support placed above the first support, the generator piezoelectric elements arranged on the first support having free ends (such as upper ends) that are curved with a first radius of curvature and the generator piezoelectric elements that are placed on the second support having free ends (such as upper ends) that are curved with a second radius of curvature larger than said first radius of curvature.

Both the number of cycles and the leakage currents are affected by the voltage that the generator piezoelectric element presents on its surfaces. In general, the capture element can have considerable dimensions, for example, a length of several metres or tens of metres, and oscillation frequency or swaying of the capture element can be very low, for example of just a few Hz or even less.

The magnets or other actuator elements that serve to interact with the generator piezoelectric elements can be arranged accordingly, or just at some specific positions. For example, a first magnet associated to the capture element can cause the displacement of a second magnet associated to the generator piezoelectric element in such a way that said deformation of the generator piezoelectric element occurs, for example, a bending of the piezoelectric element in respect of a fixed point thereof; subsequently, the generator piezoelectric element can return to its initial configuration in an oscillating manner, producing electrical energy.

The graph made up of lines or strokes alternating with dots represents the case in which the cantilever is triggered by the interaction by two magnets (MA-MA), by repulsion, according to the principle illustrated in figures 5A-5C. It can be observed how the triggering by interaction between magnets by repulsion provides for the highest levels of kinetic energy. This can be especially advantageous when the generator piezoelectric elements are arranged extending in the radial direction. Como aliviar un dolor de espalda baja . Reference is made to a gyroscopic electrical generator as the means for carrying out this conversion. In order to maximise the energy capture from the movement of the fluid that surrounds the capture element, it is preferable for the natural oscillation frequency of the capture element to correspond to the frequency of appearance of the vortices. It is understood that this increased amplitude and frequency contribute to increased efficiency in the production of electrical energy.

This arrangement can be especially useful in cases in which the supports are arranged at different distances or heights over a point where the capture element is fixed or anchored so that it sways, for example, towards one side and towards the opposite side, with regard to said point where it is fixed. As shown in figure 2, the laminar flow 300 of the wind, upon impact with the capture element 100, produces a series of vortices 301 which occur alternatively on one side and the other of the capture element 100, and with a constant distance 302 between the successive vortices on each side of the capture element 100. Therefore, on the capture element 100 a drag force 303 is produced which is substantially constant in the direction of the wind, and a lift force 304 which is substantially perpendicular to the general direction of the wind and to the direction of the drag force.

For a capture element having a specific configuration and constitution, the frequency at which the vortices are generated and at which the lift force 304 oscillates, will depend on the wind speed. The frequency of the appearance of the vortices depends on the wind speed. For example, the generator piezoelectric elements that are flat or substantially flat or similar store elastic potential energy when they are deformed.
