Abstract： |
This invention relates to a metal hetero-junction temperature sensor and its process method based on disordered multi-wall carbon nanometer tube. The temperature sensor comprises the following: multi-wall carbon nanometer tube power column filled in heat-isolation tube; metal temperature probe of carbon nanometer tube-metal heterojunction with multi-wall carbon nanometer powder column end set and tightly contacted with the carbon nanometer powder column; the conductive metal block sealed on the other end of the carbon nanometer powder column. When in work, it is first to connect electrode and outer circuit gage; then to contact the metal temperature probe and the object to be measured. In this way, the circuit can generate heat circuit changing with temperature due to the existence of the nanometer tube-metal heterojunction. |
