Accompanying drawing explanation
Fig. 1 is the longitudinally cutting structural representation of elasticity microtubule of the present utility model.
Fig. 2 is the transverse cross sectional structural representation of elasticity microtubule of the present utility model.
Embodiment
Following 1-2 by reference to the accompanying drawings, is further described the application's scheme:
A kind of microfluidic channel, comprise the body 1 of elastic polymer material, there is in body 1 fluid passage 10, the JISA hardness of this body 1 is for for 10 to 100, and being embodied as good with 20 to 50, dispersion in the tube wall of described body 1 orientations have the some one heavy micro-carbon spring 2 of circumvolution, and at least one pair of electrode 3a, 3b are arranged on described body 1, described electrode 3a, 3b are connected to oscillograph or electrical signal detection device, to obtain L(inductance), C(electric capacity) and R(resistance) characterization.
Described one heavily the micro-carbon spring 2 of circumvolution for putting down in body 1 axially-aligned, the stability that the favourable electricity consumption characterization of this orientations mode detects, and facilitate the extruded of body 1.
Described electrode 3a, 3b are parallel to body and are axially embedded in this body 1, in fact, according to detecting demand to each portion of body 1, can arrange described electrode 3a, 3b in arbitrary position on this body 1, and electrode 3a, 3b bury direction underground and also can arrange flexibly.
One heavily exists separation between the micro-carbon spring 2 of circumvolution between two, makes each one heavily to contact without direct between the micro-carbon spring 2 of circumvolution, ensures stablizing with accurate of electrical signal.
The carbon fiber diameter of the described one heavy micro-carbon spring 2 of circumvolution is 0.005-2 micron, and spiral shell footpath is 0.1-10 micron, and pitch is 0.1-10 micron, and its length is 0.05-2 millimeter.Above-mentioned one heavily the micro-carbon spring sizes of circumvolution can according to body size with detect precision and need to determine.
Described body 1 is organic siliconresin, polyurethane resin, epoxy resin, or the copolymer resin of styrenic thermoplastic elastomer.Specifically,
The product that described organic siliconresin can select Chemical Co., Ltd. of SHIN-ETSU HANTOTAI to manufacture:
1) trade name, KE-103, JISA hardness 18, JISK tensile strength 0.3MPa;
2) KE-106JISA hardness 50, JISK tensile strength 8MPa;
Describedly the Septon resin #4033(JISA hardness of Kuraray company can be adopted to be 76, tensile strength 35MPa as cinnamic copolymer resin and thermoplastic elastomer (TPE)).
Essential implementation of the present utility model is:
The resin that described body 1 uses stretchability good is conducive to sensitivity and improves, and slight pressure just can cause flexible, detects this pressure with high sensitivity; Wherein, if the JISA hardness of body 1 is too low, body 1 is too soft, and directly can cause the appearance of a large amount of signal noise, overall signal to noise ratio is too low; If the JISA much higher hard of body 1, so pressure propagation is poor, detects susceptibility too low.During general enforcement, JISA hardness 20 ~ 50 in ductility, obtain reasonable balance between elasticity and intensity.
