Abstract
The invention relates to a micro-robot based on bacteria driving. The micro-robot is put in a solution and comprises a body, an induction coil, bacterial culture colloid and trichobacteria. The trichobacteria is fixed on the bacterial culture colloid, the bacterial culture colloid and the induction coil are fixed on the body, and the induction coil is located in an alternating electric field. When the alternating electric field is used, an electric current is generated in the induction coil, the solution electrolyzes, a pH gradient field is generated to push the trichobacteria to move directionally, and the trichobacteria pushes the body to move. Compared with the prior art, the micro-robot based on the bacteria driving has the advantages of being simple in structure, easy to achieve, enough and stable in motive power and the like.

Fig. 2 is perspective view of the present invention.
The specific embodiment
The present invention is described in detail below in conjunction with the drawings and specific embodiments.
Embodiment
As shown in Figure 1 and Figure 2, a kind of microrobot that drives based on bacterium, this microrobot is placed in solution, described microrobot comprises body 1, induction coil 2, Bacteria Culture colloid 3 and flagellar bacterium 4, described flagellar bacterium 4 is fixed on Bacteria Culture colloid 3, described Bacteria Culture colloid 3, induction coil 2 are fixed on body 1, and described induction coil 2 is in alternating electric field; Apply after alternating electric field current electroanalysis solution in induction coil 2, produce the pH gradient fields and promote flagellar bacterium 4 displacements, flagellar bacterium 4 promotes bodies and moves.
(1) microrobot is placed in solution
But solution must electrolysis produce hydrogen ion, and induction coil is immersed in solution, and solution can select NaOH, potassium hydroxide etc. with alkaline solution hydroxy.
(2), induction coil adopts platinum filament
Require coil that physics, chemical change do not occur, have a chemistry stability, therefore adopt the inert metal material.
(3), applied alternating field covering solution region
Based on electromagnetic induction principle, applied alternating field makes and produces induced-current in induction coil, forms current loop in wire.Based on electrochemical principle, electrode process starts, and around coil, solution is by electrolysis, and in the process of electrolytic solution, hydrogen ion and oxygen are produced in the zone that oxidation reaction occurs, and the zone that reduction reaction occurs produces hydroxide ion and hydrogen.Therefore after hydrogen ion concentration raise, the pH value reduced, in like manner, reduction reaction place's hydrogen ion concentration reduction, the pH value increases.Produce the pH gradient fields.
(4), microrobot motion
Due to chemotaxis, flagellar bacterium spontaneously makes Chemotaxis to the pH value zone that is fit to existence in the pH gradient fields, because it is fixed on the Bacteria Culture colloid of microrobot, just promotes the robot motion.
(5), microrobot is controlled
Change frequency, amplitude and the direction of an electric field of applied alternating field, can control movement velocity, the direction of bacterium and microrobot.
Due to the microscopic dimensions of bacterium, need select light weight insulating material to make the micromachine human body and cultivate colloid; Cultured cell and bacterium on colloid are the mature technologies on organizational engineering; Due to the bacteria live condition restriction, should be noted the impact of temperature, pH value etc. in experimentation; The alternating voltage amplitude can not be excessive, and according to experiment experience, induced electromotive force should not surpass 3.0V, otherwise bacterium is lost activity; The bacterium characteristic on the robot impact greatly should select active bacterium high, pH concentration sensitivity to cultivate, as Escherichia coli; Bacterial density can not be excessive, otherwise bacterium can be intertwined mutually, runs out of steam.
