研究目的
Investigating the development of a hybrid biological photovoltaic device for self-sustainable power generation in remote and resource-limited environments.
研究成果
The engineered 3D polymicrobial biofilm device demonstrated sustainable energy production without additional organic fuels, offering a promising solution for powering unattended sensors in remote locations.
研究不足
The study's limitations include the potential for imbalanced bacterial growth and the need for further optimization of the hydrogel encapsulation process to enhance long-term stability and power output.
1：Experimental Design and Method Selection:
The study employed a 3D bioprinting technique to create a hybrid micro-BPV device with a cyanobacteria-laden hydrogel layer over heterotrophic bacteria.
2：Sample Selection and Data Sources:
Cyanobacteria (Synechocystis sp. PCC 6803) and heterotrophic bacteria (Shewanella oneidensis MR-1) were used.
3：List of Experimental Equipment and Materials:
A VitarixTM bioprinter, alginate hydrogels, PEDOT:PSS conductive polymer, Ag2O, and a PMMA chamber were utilized.
4：Experimental Procedures and Operational Workflow:
The device was fabricated on a paper substrate with an interdigitated electrode configuration, followed by bacterial inoculation and hydrogel encapsulation.
5：Data Analysis Methods:
Power generation was measured using a data acquisition system (National Instrument, USB-6212).
