When hydrogen is present, it reacts with the oxygen, reversing this effect and causing a rapid drop in electrical current. This change is fast and reversible at room temperature up to 120 °C. The ...

This change is fast and reversible at room temperature up to 120°C. The sensor was tested in various real-world scenarios, including detecting leaks from pipes, monitoring hydrogen diffusion in ...

Scientists have developed a highly sensitive, low-cost hydrogen sensor that can detect even trace ... This change is both ...
