Researchers at Binghamton University in the United States have developed a microbial bioaccumulator that is activated by absorbing moisture from the air. More about the invention To read in Small magazine.
The main goal of the creators was to invent an energy source that would not lose its properties for 100 years. In addition, the list of requirements included criteria such as compactness and the ability to generate energy on demand.
As a result, American scientists have developed a miniature coin-sized fuel cell coated with Kapton film, a material that can withstand temperatures from minus 273 to plus 400 degrees Celsius. The created bio-battery starts to produce energy if the Kapton film is removed. It can be glued in the same way, and the bioaccumulator will be in standby mode.
During experiments, scientists found that the bio-battery produced enough energy to power an LED bulb, a digital thermometer, and a clock smaller than ten. The service life of the invention was also impressive: after a week of storage at room temperature, battery performance decreased by only 2%. According to scientists, potentially such an element could remain operational for 100 years.
