Embodiment
For fully understanding purpose, feature and the effect of the utility model, by following concrete embodiment, the utility model is elaborated.
Self-powered contact lenses of the present utility model have been used the electric principle of friction, and the energy that can directly human eye be blinked or rotate is converted into electric energy.Concrete, because the micro-nano concaveconvex structure that exists, the phase mutual friction of high polymer layer surface produces static charge, the generation of static charge can make the electric capacity between the electrode change, thereby cause occurring electric potential difference between the electrode, thereby the energy that the self-powered contact lenses of the utility model application friction electricity can directly blink human eye or rotate is converted into electric energy.
As shown in figures 1 and 3, a kind of self-powered contact lenses comprise contact lenses supply unit 1, contact lenses body 2 and current-collecting device 3, wherein, described contact lenses are encapsulated in the contact lenses body 2 with supply unit 1, and described contact lenses are powered to current-collecting device with supply unit 1; Described supply unit comprises first electrode that stacks gradually, first high polymer layer, and second high polymer layer and second electrode wherein, have the micro-nano concaveconvex structure on the surface of the not multilayer electrode of at least one high polymer layer; Described first electrode and second electrode are this supply unit voltage and current output electrode.Preferably, the self-powered contact lenses can also comprise lead 4, are used for contact lenses are flowed to current-collecting device 3 with the induced charge of supply unit 1.
As shown in Figure 2, contact lenses comprise first electrode 11 that stacks gradually with supply unit 1, first high polymer layer 12, second high polymer layer 13 and second electrode 14 wherein, have micro-nano concaveconvex structure 15 on the surface that electrode is not set of at least one high polymer layer; Described first electrode 11 and second electrode 14 are this supply unit voltage and current output electrode.The utility model contact lenses are transparent with supply unit integral body.
First high polymer layer 12 and second high polymer layer, 13 materials are not both, better induced charge.Preferred first high polymer layer of the utility model and the second high polymer layer material therefor independently are selected from polyethylene terephthalate, dimethyl silicone polymer, polystyrene, polymethylmethacrylate and polycarbonate respectively.But, use in the supply unit 1 preferred 50 microns of the thickness of first high polymer layer 12 and second high polymer layer 13 at contact lenses.
At least one surface among first high polymer layer 12 and second high polymer layer, 13 apparent surfaces is provided with micro-nano concaveconvex structure 15, this micro-nano concaveconvex structure 15 is extremely micron-sized concaveconvex structure of nanoscale, the nano concavo-convex structure of preferred height of projection 50nm-300nm.
Preferred contact lenses are annular with supply unit 1 in the present embodiment, and annular interior diameter is that 7-9mm annular overall diameter is 10-14mm.
Micro-nano concaveconvex structure 15 can adopt several different methods to be prepared, for example with the silicon template compacting that the ad hoc rules bulge-structure is arranged, with sand papering metal surface and additive method.Describe a kind of preparation method of micro-nano concaveconvex structure 15 below in detail.
S1 makes the silicon template.Silicon chip is made the figure of rule on the surface with the method for photoetching.Carry out the wet technology anisotropic etching of carving of silicon chip of figure, can carve the rectangular pyramid array structure of spill, perhaps also can be with doing the cube array structure that the technology isotropic etching of carving can carve spill.Carve good template afterwards and clean up with acetone and isopropyl alcohol, all then templates are all carried out the processing of surface silicon alkanisation in the atmosphere of trimethyl chlorosilane, and the silicon template of handling well is stand-by.
S2 makes the polymer membrane with micro-nano relief structured surface.At first polymer paste is coated on the silicon template surface, vacuum outgas, the mode potpourri that silicon chip surface is unnecessary that applies with rotation removes, and forms the very thin polymeric liquid film of one deck.Whole template is solidified, peel off then, had the polymer film of specific microstructure array uniformly.
The material of the utility model contact lenses body 2 can be selected according to the material of existing contact lenses, and the utility model does not limit this, for example polymethylmethacrylate (PMMA), methacrylic acid-2-hydroxy methacrylate (HEMA) etc.It is circular that the utility model contact lenses body is generally, to adapt to the shape of eyeball.In addition, in order to adapt to eyeball to the characteristics of outer lug, the outside surface of the contact lenses body that this is circular outwards protrudes, and inside surface correspondingly caves in, and forms curved surface.
As shown in figures 1 and 3, contact lenses of the present utility model pass through lead 4 outside output currents with supply unit 1.Concrete, among Fig. 1 and Fig. 3 figure only generality lead 4 is shown, in fact use two leads 4, contact lenses are connected a lead 4 with first electrode 11 of supply unit 1 respectively with second electrode 14.Use supply unit 1 in contact lenses body injection molding process at contact lenses, in advance these transparent ring-type contact lenses are fixed with supply unit 1 and lead 4, then by conventional injection mo(u)lding, contact lenses are encapsulated in the contact lenses body 2 with supply unit 1, and an end of two leads 4 stretches out contact lenses body 2 respectively, exposes the inside surface at contact lenses body 2.It will be appreciated by those skilled in the art that the RTTY sensing mode that replaces lead in the prior art, be all distortion of the present utility model, should be within protection domain of the present utility model.
When human eye blinks or rotate, 13 surperficial mutual friction mutually produce static charge to first high polymer layer 12 with second high polymer layer, the generation of static charge can make the electric capacity between first electrode 11 and second electrode 14 change, thereby causes electric potential difference occurring between first electrode 11 and second electrode 14.The lead that first electrode 11 and second electrode 14 pass through respectively is connected to current-collecting device 3, can give current-collecting device 3 power supplies.Current-collecting device 3 can be arranged at the central authorities of recessive eyes inside surface.
Current-collecting device 3 can be the sensor that detects intraocular pressure, LED screen etc.Conventional existing intraocular uses the sensor that detects intraocular pressure all to can be applicable to the present invention.Usually be integrated with the radio-frequency transmissions assembly in the sensor, be used for the detection signal of transmission sensor.In addition, adopt conventional wireless radio-frequency to make as for external radio frequency receiving unit, be used for the detection signal of receiving sensor, thereby can characterize intraocular pressure.The utility model current-collecting device 3 can also be conventional LED screen, and contact lenses are powered to the LED screen by lead with supply unit 1, can light LED cold light lamp array, helps to look thing at dark place or amblyopia patient; Perhaps the LED screen can show blind printed words, helps the identification blind person, plays the effect of transmission information.When current-collecting device 3 is LED whens screen, the LED screen the optional position that the position can be contact lenses body 2 is set, for example be encapsulated in the contact lenses body 2, be positioned at inside surface or the outside surface of contact lenses body 2.
Such scheme comprises first-selected embodiment and when putting on record during the optimal mode of this utility model known for inventor, above-described embodiment only as an illustration the property example provide.To many alienation of the specific embodiment of exposure in this explanation, do not depart from the spirit and scope of this utility model, will be to differentiate easily.Therefore, the scope of this utility model will be determined by appended claim, and the special embodiment that describes above being not limited to.
