Combining with the advantages of NiO and four needle-like nano-ZnO
a method using Ni Nano particle doping ZnO gas sensing films under magnetic-field induction to fabricate formaldehyde gas sensor array was proposed.The gas-sensitivity of formaldehyde sensor and its mechanism is analyzed.The stability is tested in different using method.The experimental results show that thick-film surface parallel to the magnetic induction of 5 % Ni doping ZnO thick film has good stability
and at the same time formaldehyde gas-sensor has best repeatability of detection and gas-sensitivity.It can be used to fabricate formaldehyde gas detectors and has good prospects.
