Embodiment 1

[0049] A flexible moisture power generation device includes a porous top electrode, a bottom electrode and a microbial film.

[0050] Concrete preparation method comprises the following steps:

[0051] (1) Preparation of microbial film:

[0052] Take the cultured E. coli bacteria liquid, centrifuge at 6000rpm to obtain E. coli bacteria cells, then quickly resuspend with ultrapure water, repeat several times, and obtain E. coli bacteria liquid (1g wet bacteria body / 15mL bacteria liquid). Add 200 microliters of bacteria solution dropwise into the mold, and dry at room temperature at 25°C to obtain an Escherichia coli microbial film with a thickness of 18 microns.

[0053] Wherein, the mold in this embodiment is: a hollow mold constructed using a customized glass frame (the area of ​​the hollow part is 10×10 mm), and the preparation process takes a total of 6 hours.

[0054] (2) The microbial film obtained in step (1) is coated on the bottom electrode of PET-ITO, and then a por...

Abstract

The invention discloses a flexible moisture power generation device and application thereof. The invention relates to a microbial film which is prepared by drying electroactive bacteria, the electroactive bacteria comprise escherichia coli. The flexible moisture power generation device comprises a microbial film, a bottom electrode and a top electrode, one side surface of the microbial film is in fit connection with the top electrode, and the other side surface of the microbial film is in fit connection with the bottom electrode. After escherichia coli forms a film, the surface is smooth, a large number of hydrophilic groups are contained in the film, the self-healing property is high, and the film can be used as an ideal moisture absorption material. The Escherichia coli microbial film can serve as a core component of a moisture power generation device, and compared with an existing core component of the moisture power generation device, the Escherichia coli microbial film is simpler in preparation process, lower in cost and higher in power generation efficiency.

Description

technical field [0001] The invention belongs to the technical field of biomass energy, and in particular relates to a flexible moisture power generation device and its application. Background technique [0002] The development of new green and clean energy technologies is of great significance to alleviate the growing energy demand and the increasingly serious environmental pollution. Current green energy technologies mainly include marine thermal energy, wind energy, photovoltaic power generation, hydrovoltaic power generation, etc. according to their energy sources. restrictions, and the instability of its power production restricts the development of the industry. However, the moisture generator in the emerging field of "hydrovoltaic power generation" in recent years is a new type of energy harvesting and conversion device, which absorbs water molecules through the interaction between oxygen-containing functional groups in hygroscopic materials and water molecules. The ...
