Abstract
A remotely readable hydrogen detector is in the form of a tag or card that can be worn on clothing or mounted on a variety of surfaces and can be monitored from a distance for the presence of hydrogen gas. It includes a hydrogen sensor device, which changes in electrical resistivity in response to being exposed to hydrogen gas, that is incorporated into an electric detector circuit, which detects changes in resistivity of the sensor device, and, when such change in resistivity indicates the presence of some predetermined concentration of hydrogen gas, the electric circuit outputs a signal or state that indicates the presence of hydrogen to a transceiver circuit, which can transmit that information to a remote receiver or interrogator/reader via an antenna in the sensor device.
