Researchers from U.S. Argonne National Laboratory have developed flexible sensors for hydrogen vehicles. These sensors will be cheaper than previously designed hydrogen sensors because they will use only palladium nanoparticles instead of pure palladium. But they will be as efficient and could be used in many applications, like in vehicles, aircraft and portable electronics. They could even be used to detect a 'leakage of hydrogen caused by tiny pinholes in the pipe of a space shuttle.
