Striving to transform marine monitoring, researchers from Binghamton University, the State University of New York devised a tiny ‘bug’ like robot that will explore the Ocean Internet of Things . Inspired by biological digestion, an advanced machine was designed and equipped with a self-sustained energy system.
By 2035 over one trillion autonomous devices are expected to be woven into all aspects of human life as part of the “Internet of Things” , futurists say. Regardless of size, most objects will likely collect and transmit data to a central database without human intervention. Since water occupies the majority of the planet estimated at 332 million cubic miles – 71 percent, such aquatic robots could shed light on vast environments especiallyFor this reason, the U.S. Defense Advanced Research Projects Agency began a program namely the Ocean of Things.Researchers explained in the study that the bug uses microbial fuel cell technology to convert organic materials in aquatic environments into electricity through catalytic redox reactions. “To extend the MFC’s lifespan, spore-forming Bacillus subtilis is used as the anodic biocatalyst, leveraging its ability to endure harsh conditions and reactivate in favorable environments, thus enhancing the MFC’s longevity,” noted the study.The researchers further explained that a biomimetic Janus membrane with asymmetric surface wettability is integrated, enabling selective substrate intake. It extracts the nutrients from water and fuels bacterial spore production in the aquatic robot. The biobatteries likely have a shelf life of 100 years. “When the environment is favorable for the bacteria, they become vegetative cells and generate power,” said Seokheun “Sean” Choi from Binghamton University Professor Seokheun. “But when the conditions are not favorable — for example, it’s really cold or the nutrients are not available — they go back to spores. In that way, we can extend the operational life.” Bug-bots akin to small insects that are adapted for life on top of still water will be able to stride in the water via a motor. The motor is powered by microbial metabolism, fueled by organic nutrients through the Janus membrane, researchers added. “This study demonstrates the feasibility of using natural processes for technological advancement, setting new benchmarks in the design of autonomous systems,” the authors stated. Soon, the researchers will experiment with bacteria on the aquatic robots to identify which works best for yielding energy even in stressful “We used very common bacterial cells, but we need to study further to know what is actually living in those areas of the ocean,” Choi says in a university statement.“Previously, we demonstrated that the combination of multiple bacterial cells can improve sustainability and power, so that’s another idea. Maybe using machine learning, we can find the optimal combination of bacterial species to improve power density and sustainability.”As a quirky and imaginative multi-media journalist with a Masters in Magazine Journalism, I'm always cooking up fresh ideas and finding innovative ways to tell stories. I've dabbled in various realms of media, from wielding a pen as a writer to capturing moments as a photographer, and even strategizing on social media.
