Embodiment one:

The present embodiment provides the typical structures of submarine signal generating device referring to Fig. 1, comprising: floating body 1 in water is arranged On contact generator 2, contact generator 2 includes: the first flexible substrates 21,21 lower surface of the first flexible substrates successively layer The electric grade layer 22 of the first of folded setting and the first frictional layer 23 and the second flexible substrates 24,24 upper surface of the second flexible substrates according to The secondary the second electrode lay 25 being stacked and the second frictional layer 26 and undulating electrodes layer 27, wherein undaform electrode layer 27 Support is between the first frictional layer 23 and the second frictional layer 26;The first flexible substrates 21 and/or the second flexible substrates are impacted in water wave 24 act on lower undulating electrodes 27, and deformation occurs makes the first frictional layer 23 and/or the second frictional layer 26 and 27 phase of undulating electrodes layer Mutually it is contacting and separating;Signal generating unit 3, for issuing, light is thought or electric signal etc., signal generating unit 3 are connected to the first electricity Between pole layer 22 and undulating electrodes layer 27, and/or it is connected between the second electrode lay 25 and undulating electrodes layer 27.

In contact generator 2, material and the undulating electrodes layer 27 of the first frictional layer 23 and/or the second frictional layer 26 It is poor to there is friction electrode sequence in material.The power generation detailed process of contact generator are as follows: under the action of Water wave impact, the first friction Two kinds of materials of layer 23 or the second frictional layer 26 and undulating electrodes layer 27 contact with each other and electric charge transfer occur on the contact surface. After ripples are decorporated, due to the restoring force of the elasticity of 27 material of undulating electrodes layer itself, separated between two kinds of materials, and Opposite polarity contact charge is formed on each face.Since positively charged contact charge and electronegative contact charge are The potential generated on one electrode layer 22 or the second electrode lay 25 and undulating electrodes layer 27 has differences, in order to balance the potential Difference, to form the pulse current for passing through signal generating unit 3.When water wave external force applies again, due to the first frictional layer 23 or The gap distance of second frictional layer 26 and undulating electrodes layer 27 is changed, first electrode layer 22 or the second electrode lay 25 and wave The potential difference of shape electrode layer 27 occurs again, is changed the distribution of charges for reaching balance, and the charge of redistribution causes again Pass through the pulse current of signal generating unit 3.It should be noted that in the case where load (signal generating unit 3) access, the One frictional layer 23 (or second frictional layer 26) and undulating electrodes layer 27 generate opposite potential difference in separation and approach process, Therefore, the flow direction of the pulse current during two is opposite.In conclusion the power generation function of the present embodiment is in periodical external water Pulse ac electricity under the action of wave with corresponding frequencies is supplied to signal generating unit 3.

Heretofore described " friction electrode sequence ", refer to the row carried out according to attraction degree of the material to charge Sequence, two kinds of materials are in the moment to contact with each other, positive charge more negative material surface of polarity from friction electrode sequence on the contact surface It is transferred to the material surface of polarity calibration in friction electrode sequence.It is generally believed that the surface work function of this electric charge transfer and material Correlation realizes electric charge transfer by the transfer of electronics or ion on the contact surface.It should be noted that friction electrode sequence is only It is a kind of statistical result based on experience, i.e. two kinds of materials differ remoter in the sequence, and produced charge is positive and negative after contact Property and the probability that is consistent of the sequence it is bigger, and actual result is affected by various factors, for example material surface is thick Rugosity, ambient humidity and whether there is relative friction etc..

Heretofore described " contact charge " refers to that the material that electrode sequence polarity has differences that rubs at two kinds is contacting And the charge that its surface is had after separating, it is considered that, which is only distributed in the surface of material, and distribution depth capacity is only About 10 nanometers.It should be noted that the symbol of contact charge is the symbol of net charge, i.e., in the material with positive contact charge There may be the aggregation zones of negative electrical charge in some areas on surface, but the symbol of whole surface net charge is positive.

In contact generator 2, the material of the first frictional layer 23 (or second frictional layer 26) and undulating electrodes layer 27 exists Polarity difference in friction electrode sequence directly affects contact charge density, and polarity difference is bigger, and contact charge density is bigger, and More contact charges will generate bigger potential difference between two electrode layers, to improve the output work of contact generator 2 Rate.Therefore, it to be chosen at one group of material that polarity difference is big in friction electrode sequence as much as possible, for example, 23 He of the first frictional layer The material of second frictional layer 26 can select polytetrafluoroethylene (PTFE), and the material of undulating electrodes layer 27 can select copper.

Undulating electrodes layer 27 is a kind of elastic construction, can form it into wavy knot for sheet metal is heat-treated Structure, the structure can mention for the first electrode layer 22, the first frictional layer 23 and the second electrode lay 25, the second frictional layer 26 For support, and deformation is generated under water wave percussion.Undulating electrodes layer 27 or multilayered structure, in flexible thin membrane material The tow sides of material are bent to form after preparing metallic film.Pass through the metallic copper for being 50 microns in Kapton deposition thickness What film was constituted, metallic film preparation can using vapor deposition or sputtering method, and specific metal material can choose titanium or aluminium, The good conductivities such as copper, lower-cost material.
