  • Patent number: 7270002
    Abstract: A humidity sensor element, a humidity sensor device and a method for manufacturing thereof are provided. The humidity sensor element includes a substrate having a nanocomposite film as sensing material, wherein said nanocomposite film consists of carbon nanotube/perfluorinated polymer with acid functional groups in weight ratio of 0.01-20; and at least a pair of electrodes, which contact with the sensing material at one or both side(s). The nanocomposite film increases the sensitivity of humidity sensor element such that even an infinitesimal amount of moisture can be detected with minimum detection limit of 15.76 ppmv.

  • Patent number: 6517787
    Abstract: The present invention discloses an ozone generator with reduced NOx comprising an air stream generating device; a drying device; an electrical field generating unit; a high-voltage generating device; and a cooling device. The flow velocity of the air stream in the ozone generating area can be increased by the air stream generating device up to 700 s.c.c.m. The temperature in the ozone generating area can be lowered by the cooling system to lower than 10° C. The amount of NOx produced by the disclosed ozone generator can be reduced substantially.
