Scientists from the Ilmenau Technical University and the Fraunhofer Institute of Applied Solid State Physics have made a new, robust and compact ozone-sensor from indium oxide nanoparticles and blue light-emitting diodes (LEDs) on a single sensor chip. The sensor works at room temperature, unlike other such devices, and can detect ozone concentrations down to as low as 40 ppb. The team says that the device could be available to buy in as little as 18 months.
