Abstract

Device for creating optical effects on an individual. This device comprises a support (9) acceptable to the skin and able to be attached to the latter and an emissive optical device (3) and / or with adjustable optical properties, secured to said support.

Description

The present invention relates to the creation of optical effects

on an individual and

  more particularly, but not exclusively, the field of makeup.

  The present invention relates in particular to a device for concealing an imperfection of the skin and / or for creating a new and possibly variable aesthetic effect. The device according to the invention is characterized in that it comprises an acceptable support for the skin and capable of being fixed on the latter and a device

  emissive optics and / or with modular optical properties, integral with said support.

  The device according to the invention makes it possible to create new optical effects or optical effects known but hitherto generated by devices unsuitable for

be fixed on the skin.

  The optical device can be emissive.

  It is also possible to use a non-emissive optical device with properties

  modular optics, that is to say needing to be illuminated to be seen.

  In a particular implementation of the invention, the optical device is

an electro-optical device.

  Advantageously, a control device is provided for controlling the

  electric current applied to this electro-optical device.

  This control device can react according to the external environment, for example the intensity or the temperature of the surrounding lighting or to sounds or colors. The device according to the invention may include an electrical source carried by

  support or independent of the latter.

  In the case where the electric source is carried by the support, this can be constituted for example by one or more photovoltaic or thermovoltaic cells. In the case where the electrical source is independent of the support, this can

  be housed in an earring case for example.

  Preferably, the support is flexible and it is permeable to air, sweat and

  sebum and steam so as not to be uncomfortable to wear.

  2 zb 2811206 Preferably also, the face of the support applied to the skin is devoid of projecting parts, so as not to leave marks thereon after

its withdrawal.

  The support can be coated with adhesive before it is applied to the skin.

  In this case, the adhesive is preferably applied so as not to cover the entire surface of the support and / or to cover the latter with a thickness not

  uniform, to allow a certain ventilation of the skin.

  The adhesive used can be chosen from physiologically-based adhesives

  acceptable for the skin, in particular polyacrylates, polybutenes or polyesters.

  The support can also be made of an intrinsically material

  adhesive or having received a surface treatment giving it adhesive properties.

  The adhesive can still be deposited on the skin or the support just before

  the application of the latter on the skin.

  The support can be made of an electrically insulating material, in which case conductive tracks can be deposited or formed on the support to allow

  establish an electrical connection with the electro-optical device.

  The support can be transparent, so that it is difficult to detect on the

skin, or be colored.

  In the latter case, the support may have substantially the same color

  and the same dullness as the skin, in order to best blend with the latter.

  The device according to the invention can receive, on its external face, a treatment or a coating intended to give it mattness and / or to avoid reflections,

  in order to make it more difficult to detect its presence on the skin.

  The electro-optical device used can be an electroluminescence, incandescent, fluorescence, microcapsule, crystal device

  liquids, plasma or semiconductor polymers.

  This device can be chosen to create a makeup effect, possibly variable, in order to conceal an imperfection of the skin and / or

  contribute to the aesthetics of the face or body.

  The support can receive a network of electrical conductors making it possible to send current to a predetermined location, the electrooptical device possibly comprising several cells capable of being addressed individually by said network of electrical conductors in order, for example, to create variable optical effects according to

  the location on the medium and / or display messages.

  The electro-optical device can be sandwiched between two layers,

  the latter may include electrical conductors of different polarities.

  The support may include a plastic or mineral film. The support can occupy an area less than 2 cm2 for example in order to create a local optical effect, intended to catch the eye, or can extend over a larger surface, for example greater than 2 cm2, in order to obtain an effect wider. The device according to the invention is preferably intended to be able to be left on the skin for at least 15 minutes, or even a day, without generating discomfort for

this period.

  The invention will be better understood on reading the detailed description which will

  follow, non-limiting examples of implementation, and on examining the appended drawing, in which: - Figure 1 very schematically shows an example of a device according to the invention, - Figure 2 is a diagram in blocks of part of the device, and

  - Figures 3 to 7 illustrate different possibilities of producing the support.

  There is shown in Figure 1 two identical devices 1 according to

  the invention, each of which creates an optical effect on a woman's face.

  Each device 1 comprises an electrical source 6, schematically represented in FIG. 2, an active optical element 3 carried by a support 9 secured to the skin and an electrical connection means 4 making it possible to supply electrical current

  the active optical element 3 from the electrical source 6.

  In the example shown, the electrical source 6 is housed in a housing

forming an earring 2.

  The device 1 also includes control means 7 housed, in the example described, in the earring 2 and a sensor 8 connected to the control means 7, so that the latter can control the active optical element 3 in function external parameters such as for example the color of the external environment, the

  room temperature, sounds or colors.

  It is thus possible to obtain variable optical effects depending on the environment in

  which evolves the wearer of the device 1.

  The active optical element 3 can be of any known type, emissive or not.

  In particular, the active optical element 3 can be electroluminescent, incandescent, fluorescent, liquid crystal, microcapsule, plasma or

semiconductor polymers.

  Active optical elements with microcapsules are described in particular in the

U.S. Patent 6,017,584.

  Such elements include a plurality of microcapsules containing particles of different colors, capable of migrating inside the microcapsules

  according to the polarity of the surrounding electric field.

  The use of such elements is advantageous since the microcapsules substantially retain their color once the electric field ceases to be applied. Active optical elements with printed semiconductor polymers are developed by the British company CAMBRIDGE DISPLAY TECHNOLOGY and the

Japanese company SEIKO EPSON.

  Fine drops of semiconductor polymers are printed on a substrate then covered with a thin conductive film which allows them to be applied

Electric power.

  In accordance with the invention, the support 9 is compatible with a more or less frequent application to the skin, for a period which can range from about ten

minutes to several hours.

  In the embodiment described, the support 9 comprises a microperforated film 10, coated on its face intended to be applied to the skin with an adhesive 11

  and carrying on the other face the active optical element 3.

  The film 10 also includes conductive tracks 12 electrically connected by means of electrical connection 4 in order to supply electric current

the active optical element 3.

  In the embodiment described, the electrical connection means 4 consists of several conductive wires leading to the conductive tracks 12 but it is not going beyond the scope of the invention when the latter extend out of the support 9

  to establish an electrical connection between the support 9 and the source 6.

  The film 10 can be transparent or not, depending on the desired effect.

  In the example described, the support 9 has the shape of a flower with the optical element 3 placed in the middle, and the support is colored in order to obtain an effect

decorative optics.

  The optical element 3 is here a miniature light-emitting diode.

  When the device according to the invention is used with the aim of creating a variable make-up effect aiming for example to conceal certain imperfections of the

  skin, it is desirable that the support be as difficult as possible to detect.

  We prefer a transparent support or having the color of the skin, the assembly applied to the skin preferably having an outer face treated to be

  matt and not to generate reflections likely to reveal its presence.

  The active optical element 3 can extend over all or part of the support.

  When the active optical element 3 covers almost all of the support, micropassages can be provided through the active optical element to allow the

  skin located under the support to breathe.

  In the example of embodiment described, the film 10 is made of material

insulating plastic.

  It is not beyond the scope of the present invention when using a conductive support, totally or partially, in order to facilitate for example

  the power supply of the active optical element.

  The support can thus include a film of a conductive material, for example

  example of indium oxide doped with tin or a metal deposit.

  The support may include openings or draw a pattern, depending on the desired effect and the location of the body or face o the support is intended to be applied. In the example of embodiment described, the adhesive 11 is applied to the film 10 at regularly spaced points, so as to allow a certain ventilation of the

  skin under the support 9, by the microperforations 13 formed in the film 10.

  The adhesive 11 can of course, without departing from the scope of the present invention, be applied otherwise, in the form of a uniform layer or not, of constant thickness or not, this layer itself comprising microperforations ,

if applicable.

  As adhesive which can be used, mention may in particular be made of polyacrylates and

  generally any physiologically acceptable adhesive can be used.

  We can in particular use any type of adhesive already commonly used

  for the manufacture of patches intended to be applied to the skin.

  The support 9 may or may not be extensible, in order to allow for example better contact with the skin or to adapt to the shape of the region of the face or of the body.

to which it is applied.

  The film 10 and the adhesive layer 11 can be replaced by a microperforated film 20 made of a material having adhesive properties

  intrinsic, as shown in Figure 4.

  One can also use a film made of a material having, after

  appropriate surface treatment, adhesive properties.

  It is also possible to use a non-adhesive support, the adhesive being deposited on the

  skin before applying the support.

  In the embodiment described, the electrical source is located outside the

support, in an earring.

  Without departing from the scope of the present invention, it is possible to provide the support with a

electrical source.

  By way of example, FIG. 5 shows an autonomous device 25 which does not require an electrical connection to an electrical source situated outside the support. The device 25 comprises the same support 10 coated with adhesive as in

  the exemplary embodiment of FIG. 3.

  The support 10 supports an active optical element 3 and a cell 26 enabling it to be supplied with electric current, for example a photovoltaic or thermovoltaic cell. The support 10 also receives an electronic circuit 27 for controlling the active optical element 3, as a function for example of the temperature, of color, of the surrounding lighting, with a view to varying the makeup effect according to the atmosphere. light. Conductive tracks 28 are made on the support 10 to establish electrical connections between the cell 26, the active optical element 3 and the circuit

electronics 27.

  The assembly intended to be applied to the skin may also have a composite structure, in particular a sandwich structure, the active optical element being

prisoner between two layers.

  By way of example, FIG. 6 shows an assembly 30 comprising a lower film 31 intended to be applied to the skin, an upper film 32 and between the two an active optical element 3 and, around this active optical element 3, a material 33

  ensuring the maintenance of layers 31 and 32 one on the other.

  Conductive tracks 34 and 35 are produced on the layers 31 and 32 to

  supplying electric current to the active optical element 3.

  The latter can also be integrated into the support during the manufacture of the latter.

  this. By way of example, FIG. 7 shows a support 40 which includes in its thickness the active optical element 3 and which also receives conductive tracks 41 making it possible to connect the active optical element 3 to an electrical source and,

  if necessary, to means of control.

  A network of electrical conductors can be produced on the supports which have just been described, making it possible for example to apply an electric field of chosen polarity at a predetermined location on the support, chosen by the means of

  control, in order to locally create a change of state of the active optical element.

  It is thus possible to create, for example, variable optical effects from one place to another of the support or to control a liquid crystal display or microcapsules for

send a message.

  The support can be fixed on the skin or even placed on the lips or nails. The support can occupy a very small surface on the skin, and constitute

  somehow a "fly", or occupy a larger area.

  The device according to the invention will advantageously serve to obtain effects

  variable aesthetics of brightness or color.

  Of course, the invention is not limited to the exemplary embodiments which

have just been described.

  One can in particular realize the device so as to conceal the source

  electric in branches of glasses, for example.
