Bionic Jellyfish Swim Faster and More Efficiently

01-30-20

John Dabiri, Centennial Professor of Aeronautics and Mechanical Engineering, has developed a tiny prosthetic that enables jellyfish to swim faster and more efficiently than they normally do, without stressing the animals. Dabiri is envisioning a future in which jellyfish equipped with sensors could be directed to explore and record information about the ocean. "Only five to 10 percent of the volume of the ocean has been explored, so we want to take advantage of the fact that jellyfish are everywhere already to make a leap from ship-based measurements, which are limited in number due to their high cost," Dabiri says. "If we can find a way to direct these jellyfish and also equip them with sensors to track things like ocean temperature, salinity, oxygen levels, and so on, we could create a truly global ocean network where each of the jellyfish robots costs a few dollars to instrument and feeds themselves energy from prey already in the ocean."

Caltech's Unique Wind Projects Move Forward

06-10-13

John O. Dabiri, Professor of Aeronautics and Bioengineering, has big plans for a high school in San Pedro, military bases in California, and a small village on Bristol Bay, Alaska. "We have been able to demonstrate that using wind turbines that are 30 feet tall, as opposed to 300 feet tall, could generate sufficient power for wind-farm applications," Dabiri says. "One of the areas where these smaller turbines can have an immediate impact is in the military." The Office of Naval Research is funding a three-year project by Dabiri's group to test the smaller vertical-axis wind turbines (VAWTs) and to further develop software tools to determine their optimal placement. "We believe that these smaller turbines provide the opportunity to generate renewable power while being complementary to the ongoing activities at the base," Dabiri explains. [Learn More]

A Tissue-engineered Jellyfish with Biomimetic Propulsion

07-23-12

Graduate student Janna C. Nawroth, working with Professor John Dabiri and colleagues at Harvard, has turned solid element—silicon—and muscle cells into a freely swimming jellyfish.

"It is fascinating to witness the evolution of the Dabiri group's research from their initial ground-breaking work in understanding the fluid dynamics of jellyfish propulsion to the building of these complex engineered systems using biological materials," says Chair Ares Rosakis.

Wind-turbine Placement Produces Tenfold Power Increase

07-13-11

Field tests of John O. Dabiri, Professor of Aeronautics and Bioengineering, and colleagues' vertical-axis wind turbines have shown that the power output of wind farms can be increased by an order of magnitude—at least tenfold— by optimizing the placement of turbines on a given plot of land. "Dabiri's bioinspired engineering research is challenging the status quo in wind-energy technology," says Ares Rosakis, Division Chair and Theodore von Kármán Professor of Aeronautics and Professor of Mechanical Engineering. "This exemplifies how Caltech engineers' innovative approaches are tackling our society's greatest problems." [Caltech Press Release] [Videos of Turbines]
