Embodiment
The present embodiment is a kind of mechanical energy based on nano-pore and the conversion equipment of electric energy, and its basic cellular construction as shown in Figure 1, comprises and be shaped with nanoscale fluid passage---the semiconductor silicon based substrate 1 of nano-pore 2.This silicon-based substrate 1 is placed in the cavity that is full of electrolyte 3.Cavity 3 have respectively with silicon-based substrate 1 two sides relative to and pressurized after first surface---lower surface 6 and second surface---upper surface 4 that can move relative to silicon-based substrate 1.Cavity is separated upper and lower two chambeies by the two sides of silicon-based substrate 1.Lower surface 6 is connected with the positive and negative dispatch from foreign news agency pole plate 7,5 that is connected power supply 10 positive and negative electrodes respectively with upper surface 4.
Silicon-based substrate 1 adopts the sheet silicon-based wafer of thickness 0.5-0.7mm to make, as shown in Figure 2, the miniature cavity 1-1 of column type of the surface distributed radius 0.05-0.30mm of silicon-based wafer, the THICKNESS CONTROL at the bottom of chamber is at 40nm-1um, as shown in Figure 3, at the bottom of chamber, be shaped with respectively nano-pore spaced apart 2.
Its main manufacturing process steps is:
Step 1: clean silicon-based wafer, adopt Microelectronic etching technique to be etched into the miniature cavity of proper alignment, and chamber base thickness degree is controlled to 40nm-1um, adopting microelectronic technique etching or the semiconductor silicon based substrate 1 of high-energy heavy ion irradiation, columned nano-pore 2 arrays make to distribute at the bottom of the chamber of miniature cavity; Nano-pore 2 radiuses are 5nm(diameter 10nm), axial length is that the chamber base thickness degree of silicon-based substrate 1 is 40nm-1um;
Step 2: the silicon-based substrate of making cylindric nano-pore 2 is carried out after clean, be placed in the cavity that holds electrolyte 3;
