Detailed description of the invention
With embodiment, this utility model is further described below in conjunction with the accompanying drawings.
As shown in Figure 1.
The cell temperature transducer of a kind of improvement, including two glass-micropipes 1, described two glass-micropipes 1 are bonded together side by side.Irrigate different conducing composite materials in every glass-micropipe 1 respectively, and mutually fusion condenses into hetero-junctions 5 after front end port flow goes out.According to Seebeck effect, the absolute thermo-electromotive force produced due to two kinds of metallic composites is different, voltage difference can occurs at its two ends.Further respectively have the conductor 3 being connected with conducing composite material in described every glass-micropipe 1, the voltage difference produced can be drawn, then measure this voltage difference by high-accuracy voltage table.Then, by setting up the functional relationship between voltage difference and temperature, this hetero-junctions can be made to possess the function of thermometric.The front end of described every glass-micropipe 1 is semi-conical, and two glass-micropipe 1 front-end port mutually against, control, to facilitate, the speed that conducing composite material therein flows out, and the formation of hetero-junctions 5.Described conducing composite material is respectively Ag nano-mixture 2 and Ni nano-mixture 4.Wherein, described Ag nano-mixture 2 is mixed by Ag nano-particle and PDMS (polydimethylsiloxane Polydimethylsiloxane)；Described Ni nano-mixture 4 is mixed by Ni nano-particle and PDMS.PDMS is to have preferable mobility under flexible high molecular material, room temperature, it is simple in the micro-pipe of implantation glass.At the same time it can also be by adding certain cross-linking agent so that it is solidify at a certain temperature.The granular size of described every kind of mixture is 20x10-6Mm～5x10-3Mm, and the mixed proportion of PDMS and nano-particle is volume ratio 7:3.Described conductor 3 is respectively the Ag silk corresponding to Ag nano-mixture 2 and the Ni silk corresponding to Ni nano-mixture 4, and its diameter is 0.3mm.Preferably, a diameter of 0.0005mm-0.05mm of described every glass-micropipe 1 front-end port, it is simple to control conducing composite material and flow out from this port, and form the hetero-junctions of suitable size.
Using method of the present utility model is: be first placed in mixture of ice and water by hetero-junctions, measures its voltage difference by the high-accuracy voltage table being connected with Ag silk and Ni silk, and sets up the functional relationship of voltage and temperature.Then, this utility model is placed in high accuracy three axle and controls on platform, and observed by microscope and operate so that it is the temperature measuring head of leading section is close or punctures entrance cell, carries out temperature survey.
This utility model is not directed to part and the most same as the prior art prior art maybe can be used to be realized.
