Background technology
About the method for sending out of the pressure signal of a plurality of points of induction on the two-dimensional surface, known have a placement force sensor on each aspect on the face of two dimension, detects the method that pressure on each aspect obtains the pressure distribution on the two-dimensional surface.
But the method for placing a plurality of pressure transducers on each aspect on the two-dimensional surface needs a large amount of pressure transducers, and wiring will be very complicated when large tracts of land is taken in wiring.
Summary of the invention
Purpose of the present invention has provided the simply constructed two-dimensional surface pressure sensor apparatus of the soft inductive material of new application and has constructed method for designing.
And, the two-dimensional surface pressure transducer of the softness that the another one purpose of patent of the present invention provides.Be to form by the material of softness on the whole two-dimensional surface sensor senses face, can be crooked arbitrarily, distortion.Needing to help the application of the two-dimensional surface pressure transducer of soft-surface.As, can be used as the application of soft robot skin as people's robot of future generation etc.
First summary of the invention of present patent application is to have invented the structure method for designing that the flexible material of induction pressure is applied to the two-dimensional surface sensor of two-dimensional surface sensor.Be to add soft electrode on the flexible material upper and lower surface of induction pressure that strip is distributed, and this has been added the face of two two dimensions of composition that the strip pressure transducer of soft electrode is arranged side by side.Two planes are folded mutually up and down, when folded mutually up and down, make on the face arbitrarily the soft pressure transducer of the bilevel strip of any become to intersect and form the two-dimensional surface sensor.
Second summary of the invention of the present patent application is that this two-dimensional surface sensor device consists of the following components: a, the soft sensor of strip pressure; B, two-layer structure up and down; C detects loop and communication module; D, distributional analysis and expression software module.
In addition, the 3rd content of the present invention is to judge position and the shiftable haulage line that draws each point on the two-dimensional surface sensor with the soft sensor dynamic waveforms of two strips to intersecting on the big force that take place when mobile on two dimensional surface according to the time sequencing of spot pressure that enters the two-dimensional surface sensor and spot pressure.
The explanation of effect about invention
According to the invention of the present patent application, for the two-dimensional surface pressure transducer, the material by softness on the face of its induction pressure constitutes.Induction pressure part on the whole like this two-dimensional surface is made of flexural deformation arbitrarily fully flexible material.This helps using more widely of two-dimensional pressure sensor.As: make the carpet shape, be placed on the hotel, be used for the situations such as route distribution of perception personnel when walking about and walking about in the shop; Also activity situation of perception car amount and pedestrian etc. on the road surface that can place.
The explanation of preferred plan during the invention process
One, the explanation of soft inductive material strip pressure transducer intersection placement positioning perception.Localization method during at first with regard to the position of pressure on the perception sensitive surface of the two-dimensional surface sensor in the present patent application describes:
For the two-dimensional surface sensor, when to perceive the size of pressure suffered on its face, also want to perceive exactly the suffered distribution that gets pressure on its face.
Fig. 1 is the strip pressure transducer synoptic diagram among the present invention.
Be the soft inductive material of the senses change in pressure of flexible material between two soft electrodes up and down.This softness inductive material can be the elastomeric material of having sneaked into small building material.When up and down the pressure between two electrodes changes, the small structure generation alteration of form of elastomeric material inside, thereby its internal electric characteristic also will change, and the measurement loop detects soft feeling and answers the variation of the electrical specification of material internal to export as pressure signal.
Fig. 2 is the synoptic diagram of the pressure transducer of two strips when intersecting.
Point of crossing in Fig. 2, when A point and B point are exerted pressure respectively, only exert pressure and be in the point of crossing, on the sensor of two strips, can detect pressure simultaneously, when exerting pressure, the A point have only the strip sensors A to detect, exerting pressure at the B point is but that strip sensor B can detect will detect less than pressure on the strip sensors A and be applied in.
Fig. 3 is the synoptic diagram of the soft sensor of two group leader's strips in length and breadth of distributing on the face of two dimension.When exerting pressure more arbitrarily on the face in two dimension, producing the pressure variation simultaneously on two two strip sensors in length and breadth, thereby when obtaining the pressure sizes values of this point, can determine this some position on two-dimensional plane by this point.
At the two-dimensional surface pressure transducer shown in the figure three during when the position of on two-dimensional surface, determining a plurality of points and course, utilize each in the time that enters the soft sensor of two-dimensional surface and multidate information that applied pressure changes on to spot pressure analyze and judge the position and the course at each place on the two-dimensional surface sensor.
Two, utilize the application examples of two-dimensional surface sensor of the present invention:
The system outline of the above-mentioned two-dimensional surface sensor of being made up of the soft pressure transducer of cross one another strip is represented by Fig. 4.On two-dimensional plane, by two-layer composition up and down, promptly, ground floor is formed a plane side by side by the soft sensor of strip, the second layer is by same being made up of the soft pressure transducer of strip, but bilevel strip pressure transducer intersects mutually, also can be interweaved by the soft sensor of the soft strip pressure of strip and form.
By detecting the time dependent pressure waveform of each pressure transducer, and this time dependent pressure waveform is transferred to by the A/D transducer analyzes and display module among Fig. 4 by detecting the loop.Analyze and detection module according to the pressure waveform of each sensor curve of time variation at any time, analyze and judge, the foundation that finds in the same time in length and breadth the waveform of dynamic change same in two groups of soft pressure transducers to move as spot pressure, thereby judge the circuit that spot pressure moves, according to the size and the variation of detected pressure waveform, analysis meter is calculated the size of the time dependent force value of each spot pressure simultaneously.
