Researchers at the Bio-Inspired Materials and Devices Laboratory at Virginia Tech have developed and are testing a hydrogen fuel powered robotic jellyfish. The jellyfish consists of a silicone bell structure with nano-platinum catalyst-coated multi-wall carbon nanotube (MWCNT) sheets, wrapped on the surface of nickel–titanium (NiTi) shape memory alloy. As a mixture of oxygen and hydrogen gases makes contact with the platinum, the resulting exothermic reaction activates the nickel–titanium (NiTi)-based shape memory alloy which flexes thus causing the jellyfish to propel itself.
