Abstract :
A novel nanoparticle-integrated hydrogen microsensor with a very fast response time at room temperature is presented in this work. The sensor was developed by integrating indium dioxide (ln2O3) doped polycrystalline tin dioxide (SnO2) nano particles on interdigitated electrodes with a 5 mum spacing. In this sensor, we obtained a sensor response time as fast as 100 seconds with sensitivity as high as 3,700 for room temperature hydrogen detection.
