background
For small electronic devices, biosensors, medical sensors, the power supply system is particularly critical.Today, let us first look at the United States Binghamton University Department of electrical and computer science assistant professor Seokheun Choi developed bio-battery system:
The first is a microbial fuel cell, it can run in a few drops of dirty water on the bacteria, the appearance of a bit like a origami dart.

The other is a paper-based biofuel cell that provides energy by bacteria that not only supplies power to biosensors, but also can be used to purify the environment because microbes can break down contaminants.

technology
Seokheun Choi says the microfluidic chip lab system, which generates energy for itself, is particularly critical for stand-alone, self-sustaining, point-of-care medical diagnostic devices running in resource-constrained and remote areas. Said that miniaturized bio-solar cells (micro-BSCs) will be the most suitable power source, because this technology is similar to the Earth's natural ecosystem.
Choi said:
The miniaturized bio-solar cells provide self-sustaining renewable clean energy through the photosynthesis and respiration of microbial circadian cycles, but this technology has not yet been translated into practical applications because its power is relatively low and the life cycle is relatively Short.
Choi and Ph.D. student Lin Liu have designed a miniaturized microfluidic bio-solar cell with high electrical and long-term operational capabilities that will provide practical and sustainable power supply for chip lab applications.
value
In the existing micro-bio-solar cells, this micro-solar cells can produce the highest power density and the longest running time.
Choi said:
The device facilitates the study of breakthroughs in the research of biological light energy technology breakthroughs, and it facilitates the development of this technology in a resource-constrained and remote area independent operation, self-sustaining, fixed-point care diagnostic equipment Continuous power application direction.
