Metal Nanoparticle Sensors
Currently only available as a palladium nanoparticle based hydrogen gas sensor. The sensor is mounted onto an 8-pin TO-5 or TO-8 package. Upon being exposed to hydrogen gas, the surface area of the nanoparticles increases and creates shorts within the nanoparticle network. These shorts change the electrical conductivity.
