Scientists at the U.S. Department of Energy’s (DOE) Argonne National Laboratory and Northwestern University have discovered that common bacteria can turn microgears when suspended in a solution, providing insights for designs of bio-inspired dynamically adaptive materials for energy.

“The ability to harness and control the power of bacterial motion is an important requirement for further development of hybrid biomechanical systems driven by microorganisms,” said Argonne physicist and principal investigator Igor Aronson. “In this system, the gears are a million times more massive than the bacteria.”
