Description

摩斯码生成的T型微流控芯片装置
技术领域
本发明涉及一种微流控芯片装置，尤其是一种通过控制主通道内不同长度的液滴间距组合出摩斯码来实现信息传递的装置。
背景技术
微流控技术及微流控芯片是近年来迅速发展的一个多学科交叉领域，在生物、化学分析、信息处理等方面有广泛应用。目前制备微型液滴的方法主要有使用喷嘴装置和使用微流控设备两种，微流控芯片设备制备原理如下：
两种互不相溶的液体（如水和油）相接触时由于表面张力的作用会形成相界面。将分别在不同通道中流动的互不相溶的连续相和分散相由压力或体积驱动，使两种流体在通道的交汇处接触，由于连续相对分散相的剪切或挤压作用，使得表面张力不足以维持界面稳定而发生断裂，进而生成分散相液滴。
相比于喷嘴等借助外部动力生成液滴的装置，微流控芯片装置只需要控制两相流体的流量比，黏性等物性因素来控制生成液滴的长度与生成频率，可实现对液滴尺寸的精准控制。
摩斯码在无线电信号传输，电子信息传递等领域有着广泛应用。通过点、横之间的组合来达到信息传递的目的。本发明中通过控制两相流体的入口流量来控制生成液滴的尺寸，从而在微流通道内形成类似于“点”与“横”的液滴，组成不同的摩斯码来达到信息传递的目的。
发明内容
本发明是要提供一种摩斯码生成的T型微流控芯片装置，控制T型微流控芯片产生长短不同的液滴来类比与摩斯码中的“点”与“横”，通过微通道中“点”液滴与“横”液滴的变换组合，产生不同的摩斯码，并通过通道尾部的激光传感器来转换成相应的脉通信号，来达到信号传递的目的.
为实现上述目的，本发明的技术方案是：一种摩斯码生成的T型微流控芯片装置，包括T型微流控芯片、激光发射器、激光接收器，所述T型微流控芯片的微通道主通道前部设有连续相流体通道入口，尾部设有微通道出口，T型微流控芯片的微通道次通道设有分散相流体的通道入口，主通道尾部处设有激光发射器和激光接收器，通过控制从分散相流体的通道入口注入的分散相流体的流量来生成长液滴和短液滴，并在微通道主通道内显示出摩斯码的形式；所述激光发射器射出激光射线穿过主通道，使长度不一的长短液滴通过主通道时，输出激光强度的脉冲信号由激光接收器接收，以此来传递其所代表的摩斯码信号。
所述T型微流控芯片的主通道注入的连续相流体中混入吸光物质，使混合后的连续相液体对摄入激光射线的强度显著削弱，而次通道注入的分散相流体为单组份液体，不影响激光射线的穿透性。
本发明的有益效果是：控制T型微流控芯片产生长短不同的液滴来类比与摩斯码中的“点”与“横”，通过微通道中“点”液滴与“横”液滴的变换组合，产生不同的摩斯码，并通过通道尾部的激光传感器来转换成相应的脉通信号，来达到信号传递的目的。相比于前者，该装置能借助微液滴产生明确的摩斯码信号，使新得到的摩斯码的传递可视化，更易于实现信息的准确传输与控制。
附图说明
图1为摩斯码生成的T型微流控芯片装置示意图；
图2 为摩斯码脉冲图像。
具体实施方式
下面结合附图与实施例对本发明作进一步说明。
如图1所示，本发明的摩斯码生成的T型微流控芯片装置，包括T型微流控芯片、激光发射器5、激光接收器6。T型微流控芯片的微通道主通道前部设有连续相流体通道入口1，尾部设有微通道出口7，T型微流控芯片的微通道次通道设有分散相流体的通道入口2，主通道尾部处设有激光发射器5和激光接收器6，通过控制从分散相流体的通道入口2注入的分散相流体的流量来生成长液滴和短液滴，并在微通道主通道内显示出摩斯码的形式；激光发射器5射出激光射线穿过主通道，使长度不一的长短液滴通过主通道时，输出激光强度的脉冲信号由激光接收器6接收，以此来传递其所代表的摩斯码信号。其中，生成的长液滴3用来代表摩斯码中的“—”，生成的短液滴4用来表示摩斯码中的“·”。
T型微流控芯片的主通道注入的连续相流体2中混入吸光物质，使混合后的连续相液体对摄入激光射线的强度显著削弱，而次通道注入的分散相流体为单组份液体，不影响激光射线的穿透性。
现对该设备摩斯码传递过程进行说明：在连续相液体中混入吸光物质，使混合后的连续相液体对摄入激光射线的强度有显著的削弱，分散相为单组份液体，不影响激光射线的穿透性。将连续相液体自连续相流体通道入口1处注入，分散相液体自分散相流体的通道入口2处注入，调节连续相的流量可以生成如长液滴3和短液滴4所示的长短液滴，由于连续相液体对激光射线强度的削弱性，当尺寸不一的液滴穿够激光发射器5发射的激光射线时，在激光接收器6中会接收到持续时间不一且不同强度的激光，经过处理后的激光强度信号会显示出如图2所示的摩斯码脉冲图像，以此达到传递信息的目的。例如图2中显示的脉冲图像表示的摩斯码为“— · · —”，其表示的意思为英文字母“X”。
