Description
Technical field
The present invention relates to a kind of material, particularly a kind of pressure sensitive material.
Background technology
Touch sensor is the sensor imitating feeling function in robot, for mechanical finger, and sense
Know that pressure is one of very important project.Sense of touch is the people's important sensory function when directly contacting with external environment, grinds
It is one of developing key problem in technology of robot that system meets the touch sensor required.Along with the development of microelectric technique and various
The appearance of organic material, it has been proposed that the research and development proposal of diversified touch sensor, such as carbon containing sponge type pressure sensing
Device.Carbon containing sponge type pressure transducer, is usually the elastomer constituted on substrate equipped with carbon containing sponge, by contact object
After pressure, the resistance of carbon containing sponge reduces, and measures the size of the electric current flowing through carbon containing sponge, it may be determined that compression degree.
In prior art, it is provided with the pressure sensitive materials application of pressure responsive element to mechanical finger, pressure sensitive
The sensitivity that Materials Measurement arrives is the highest, and it is less to measure scope.
Summary of the invention
The problems referred to above existed in view of prior art, it is an object of the invention to provide a kind of pressure sensitive material, add
Measure the sensitivity of pressure, increase the scope measuring pressure.
In order to solve above-mentioned technical problem, the invention provides a kind of pressure sensitive material, including base material be arranged at institute
Stating the multiple pressure responsive element in base material, described base material is made up of pressure sensing layer and cushion, multiple described pressure sensitives
Element is serially connected and is uniformly distributed in described pressure sensing layer.
As preferably, described cushion is silica gel material and is wherein evenly arranged with multiple and described pressure responsive element position
Put corresponding buffer cell.
As preferably, described buffer cell can link with adjacent buffer cell when pressurized and transmit pressure to it.
As preferably, multiple described buffer cells are the cavity that form and dimension is identical.
As preferably, described cavity is elliposoidal bubble.

Detailed description of the invention
With specific embodiment, the pressure sensitive material of the present invention is described in further detail below in conjunction with the accompanying drawings, but does not makees
For limitation of the invention.
As it is shown in figure 1, the invention discloses a kind of pressure sensitive material, including base material and in being arranged at described base material many
Individual pressure responsive element 3, described base material is made up of cushion 1 and pressure sensing layer 2, and multiple pressure responsive element 3 are serially connected
And it is uniformly distributed in pressure sensing layer 2.Deform when cushion 1 receives pressure, be positioned at the feeling of stress of pressure sensing layer 2
Answer element 3 to translate into the signal of telecommunication to measure.When measured pressure is less, cushion 1 the most also can
Deform, thus the pressure that the cushion 1 deformed can be transmitted by pressure sensing layer 2 further reacts, thus
Add sensitivity.
Further, cushion 1 for silica gel material and is wherein evenly arranged with multiple relative with pressure responsive element 3 position
The buffer cell 4 answered.Buffer cell 4 is corresponding with pressure responsive element 3 position, thus pressure responsive element 3 can preferably connect
Receive the pressure that buffer cell 4 is transmitted.Buffer cell 4 in cushion 1 can be formed as multilamellar, and the buffer cell 4 of every layer
Buffer cell 4 interlaced arrangement with adjacent two layers.
In the present embodiment, buffer cell 4 can link with adjacent buffer cell 4 when pressurized and transmit pressure to it.
When measured pressure is bigger, the measurement scope of single pressure responsive element 3 is less, buffer cell 4 energy in cushion 1
The buffer cell 4 being enough adjacent links thus transmits pressure to adjacent buffer cell 4, and multiple buffer cells 4 all become
Shape, the deformation of each reception all can be reacted by the multiple pressure responsive element 3 corresponding with buffer cell 4, pressure sensing layer 2 energy
The pressure limit that enough measurements are bigger, thus increase tonometric scope.
Further, for the ease of processing and fabricating, multiple buffer cells 4 are set to the cavity that form and dimension is identical.Shape
The pressure that shape and the identical cavity of size also contribute to receiving transmits uniformly.
In an embodiment, cavity can be elliposoidal bubble.Certainly, the shape of cavity can also be other shapes, such as ball
Shape or equilateral triangle, specifically can be according to practical situation depending on.And both can fill gas in cavity, such as air, it is also possible to fill out
Topping up body, such as water.The fluid filled in it should be noted that cavity can not be with the material generation chemical reaction of cushion 1.
Further, cushion 1 is coated with a protective layer 5.In actual product, pressure is delivered to by protective layer 5
Cushion 1, passes to pressure sensing layer 2 then.
In the present embodiment, protective layer can be wear-resisting PVC material.
In the present embodiment, owing to varistor 3 has relatively low price and higher precision, pressure responsive element 3 is elected as
Varistor.It is of course also possible to select inductance pressure transducer, capacitance pressure transducer.
Further, processing and fabricating for convenience, pressure sensing layer 2 be also made up of silica gel material and with cushion 1 one
Arrange.
Above example is only the exemplary embodiment of the present invention, is not used in the restriction present invention, protection scope of the present invention
It is defined by the claims.The present invention can be made respectively in the essence of the present invention and protection domain by those skilled in the art
Planting amendment or equivalent, this amendment or equivalent also should be regarded as being within the scope of the present invention.
