Embodiment 1

[0038] Such as Figure 5 Shown, the effect of voltage on the rupture of 400nm Au film in different conductive media.

[0039] A gold film having a thickness of 400 nm and a diameter of 1.4 mm is used as a valve film combining an electrode having a mixture of silver and carbon ink (50% w / w). NaCl conductive medium was prepared by adding 0.4M NaCl to PBS buffer. The CsCl conductive medium was prepared by adding 0.4M CsCl to the PBS buffer. Different voltages of 3, 4 and 5 volts were applied to the electrodes made of 50% carbon ink. In the presence of each conductive medium, 50% of the silver ink corrodes the gold film, and the average time for the film rupture of each conductive medium is measured.

[0040] The results are shown in Table 1 below. When the concentration of sodium or cesium ions is increased, the corrosion of the conductive film is improved. At 3 volts, the effects of the two ions are similar, however, as a higher voltage is applied, the accelerated corrosion of the...

Embodiment 2

[0044] Such as Image 6 It shows the effect of applied voltage on the rupture of 7.2 μm Al film in different conductive media.

[0045] An aluminum film having a thickness of 7.2 μm and a diameter of 1.4 mm was used as a valve film combining an electrode composed of a mixture of silver and carbon ink (50% w / w). NaCl conductive medium was prepared by adding 0.4M NaCl to PBS buffer. The CsCl conductive medium was prepared by adding 0.4M CsCl to the PBS buffer. In the presence of each conductive medium, different voltages of 3, 4, and 5 volts were applied through the electrodes to corrode the aluminum film, and the average time for the film rupture of each conductive medium was measured. The results are shown in Table 2 below.

[0050] Such as Figure 7 It shows the effect of CsCl concentration on the rupture of 7.2μm Al and 400nm Au films at 4V.

[0051] An aluminum film with a thickness of 7.2 μm and a gold film with a thickness of 400 nm each having a diameter of 1.4 mm were used as the conductive film of the bonding electrode, the electrode including carbon ink for screen printing of aluminum and silver and carbon for gold Screen printing mixture of ink (50% w / w). Conductive CsCl media with different ionic strengths were prepared by adding 0.2M to 0.6M CsCl to the PBS buffer. In the presence of conductive media with different CsCl concentrations, a fixed voltage of 4 volts was applied to the electrode to corrode the film, and the average time for film rupture was measured. The results are shown in Table 3 below.

Abstract

The invention discloses an electrolytic film valve and a manufacturing method thereof. The electrolytic film valve comprises a substrate, a conducting film, an electrolysis cathode, an electrolysis anode, an insulating layer and a liquid accumulator. The substrate and the liquid accumulator are connected together. The liquid accumulator is internally provided with a conducting medium. The conducting film is arranged in the substrate. The electrolysis cathode and the electrolysis anode are arranged on the surface of the substrate. The insulating layer is arranged on the electrolysis cathode andthe electrolysis anode. The manufacturing method of an electrolytic film comprises the steps of depositing the conducting film on an opening of the substrate; printing the electrolysis anode on the substrate; printing the electrolysis cathode on the substrate; and closing the electrolysis anode, the conducting film and the electrolysis cathode into the liquid accumulator. By means of the electrolytic film valve and the manufacturing method of the electrolytic film, a great number of air bubbles are prevented from being generated, electrolysis can be conducted more stably, and passing efficiency of an electrolysis micro-channel can be guaranteed.

Description

Technical field [0001] The invention relates to the technical field of flow control, in particular to an electrolytic membrane valve and a manufacturing method thereof. Background technique [0002] In medical diagnostic devices or drug delivery devices, it is usually necessary to control the input liquid to pass through individual holes or microchannels at predetermined time intervals. To achieve this, a variety of valve and pump technologies have been developed, most of which utilize flexible webs, pneumatic devices, complex capillary systems, thermal or light actuated polymers, rigid beads or molten expandable materials to drive fluid through channels . It can also prevent the passage of fluid when needed. However, most of these systems require the use of large and expensive peripheral braking equipment. However, due to the lack of robustness and reliability of these devices, they cannot be used in portable handheld diagnostic devices or implantable drug delivery devices. ...
