Researchers succeed in generating energy through bacteria

Researchers from Binghamton University College of Engineering have developed a bio-battery that can generate electrical energy based on the interactions of bacteria.

Among the problems that Professor Seokhyun Choi and colleagues encountered was short battery life, which ranged from just a few hours.

Although this may be useful in some cases, long-term monitoring in remote areas requires a longer supply of electricity.


In their new research paper, published in the scientific journal "Power Sources", "the researchers developed a bio-battery that lasts for several weeks of electrical energy supply at a time," according to the TechExplore website. According to the site, “the battery can be assembled together to improve the resulting electrical tension and strengthen the current.”

In addition, he pointed out that “the previous Choi batteries contained two types of bacteria that interact with each other to generate electrical energy, but the new battery uses three types of bacteria in separate vertical chambers,” explaining: “A type of bacteria generates organic food depending on the composition.” photosynthesis, to feed the other two species.”

He continued, "The bacteria at the bottom generate electricity, while the bacteria in the middle produce chemicals to improve the transmission of electrons." The researcher considered that “the most difficult applications of the Internet of Things are wireless sensor networks, which are used in remote areas with difficult environments, and their devices are far from the electrical supply network, and it is difficult to access them in order to replace traditional batteries when they run out of power.

“While these networks allow all parts of the world to be connected together, their continuous supply of power is a prerequisite.”

Choi added: “Now we have reached 5G technology, and within ten years we will have reached 6G technology,” noting that “with the help of artificial intelligence, we will have a huge number of self-operating smart devices in very small sizes, and it will be difficult to supply them with electricity, especially In difficult-to-connect environments, we will need small batteries to power them.” The professor compares these tiny batteries, measuring 3 centimeters in length and width, with LEGO parts that can be assembled and shaped in many ways depending on the electrical need of the device.

In upcoming research, he hopes to develop a method that will allow the batteries to float on water and perform self-repairing for damage caused by the harsh environment.

"My ultimate goal is to make it very small, and we'll call it smart dust, and a group of bacteria can then generate the electricity needed to power the devices," he added.
