Description
Technical field
The present invention relates to a kind of robot, especially relate to a kind of microrobot driven based on antibacterial.
Background technology
In recent years, the type of drive for robot has carried out numerous studies both at home and abroad, and novel driving principle is extremely important for the range of activity expanding the mankind, utilizes bio-energy, and the particularly exploration of miniature organism energy the most just starts.Utilize the energy of miniature organism, one new research field when moving by controlling miniature organism thus drive robot motion.
Energy supply is the key in microrobot miniaturized design and significant challenge, utilizes the biological energy such as antibacterial to drive as the energy of microrobot and is one and effectively attempts.Research antibacterial depends on microrobot in a liquid and promotes the environmental simulation of robot motion can promote, with experimental technique etc., the use controlling bacteria motility and promote robot in the development of the industries such as health care, environment and chemistry, due to the development of nanotechnology, this microrobot with low cost has very useful prospect.But the microrobot that current microorganism drives generally exist be short of power, the defect such as state labile.
Summary of the invention

Accompanying drawing explanation
Fig. 1 is the main TV structure schematic diagram of the present invention；
Fig. 2 is the perspective view of the present invention.
Detailed description of the invention
The present invention is described in detail with specific embodiment below in conjunction with the accompanying drawings.
Embodiment
As shown in Figure 1 and Figure 2, a kind of microrobot driven based on antibacterial, this microrobot is placed in solution, described microrobot includes body 1, induction coil 2, antibacterial culturing colloid 3 and flagellar bacterium 4, described flagellar bacterium 4 is fixed on antibacterial culturing colloid 3, described antibacterial culturing colloid 3, induction coil 2 are fixed on body 1, and described induction coil 2 is in alternating electric field；After applying alternating electric field, current electroanalysis solution in induction coil 2, produces pH gradient fields and promotes flagellar bacterium 4 displacement, and flagellar bacterium 4 promotes body to move.
(1) during microrobot is placed in solution
Solution must can be electrolysed generation hydrion, and induction coil is immersed in solution, and solution may select sodium hydroxide, potassium hydroxide etc. with alkaline solution hydroxy.
(2), induction coil uses platinum filament
Require that coil does not occur physics, chemical change, there is a chemical stability, therefore use inert metal material.
(3), applied alternating field covers solution region
Based on electromagnetic induction principle, applied alternating field makes to produce in induction coil faradic current, forms current loop in tinsel.Based on electrochemical principle, electrode process starts, and coil surrounding medium is electrolysed, and during electrolytic solution, occurs the region of oxidation reaction to produce hydrion and oxygen, occurs the region of reduction reaction to produce hydroxide ion and hydrogen.Therefore after hydrogen ion concentration raises, pH value reduces, and in like manner, at reduction reaction, hydrogen ion concentration reduces, and pH value increases.Produce pH gradient fields.
(4), microrobot motion
Due to chemotaxis, in pH gradient fields, flagellar bacterium spontaneously makees Chemotaxis to the pH value region of applicable existence, because it is fixed on the antibacterial culturing colloid of microrobot, just promotes robot motion.
(5), microrobot controls
Change the frequency of applied alternating field, amplitude and direction of an electric field, antibacterial and the movement velocity of microrobot, direction can be controlled.
Due to the microscopic dimensions of antibacterial, light weight insulating material need to be selected to make micromachine human body and cultivate colloid；Colloid is cultivated cell and antibacterial, is the mature technology in tissue engineering；Owing to bacteria live condition limits, experimentation should be noted the impact of temperature, pH value etc.；Alternating voltage amplitude can not be excessive, and according to experiment experience, induction electromotive force, no more than 3.0V, otherwise can make antibacterial lose activity；Bacteria characteristic on robot impact greatly, should select activity height, the antibacterial of pH concentration sensitive to cultivate, such as escherichia coli；Bacterial density can not be excessive, and otherwise antibacterial can mutually be intertwined, and runs out of steam.
