研制了一种精度高、耐用性好、响应快、稳定性好、线性输出的呼气式酒精传感器。传感器系统的关键技术是细镍线圈和CoOx/CuO/Al_2O_3新型催化剂。采用电泳法涂覆催化层，在镍线圈上形成中空的圆柱体。较大的催化层比表面积、较大的镍线圈电阻率温度依赖性和较高的选择性使其能够高灵敏度地检测70~400ppm的水平。
The authors developed breath alcohol sensor with high accuracy, good durability, quick response, stability and linear output. Key technologies of sensor system are fine Ni coil and new catalysis of CoOx/CuO/Al2O3. Catalyst layers, which are coated by electrophoresis, are designed to form hollow cylindrical body on Ni coil. Large surface area of catalyst layer, large temperature dependence of Ni coil resistivity and high selectivity enable to detect level of 70~400ppm with high sensitivity.
