In this paper, we have developed an in-vehicle wireless driver breath alcohol detection (IDBAD) system based on Sn-doped CuO nanostructures. When the proposed system detects the ethanol trace in the driver`s exhaled breath, it can alarm and then prevents the car to be started and also sends the location of the car to the mobile phone. The sensor used in this system is a two-sided micro-heater integrated resistive ethanol gas sensor fabricated based on Sn-doped CuO nanostructures. Pristine and Sn-doped CuO nanostructures were synthesized as the sensing materials. The micro-heater is calibrated to provide the desired temperature by applying voltage. The results showed that by Sn-doping in CuO nanostructures, the sensor performance can be significantly improved. The proposed gas sensor has a fast response, good repeatability along with good selectivity that makes it suitable for being used in practical applications such as the proposed system.
在本文中,我们开发了一种基于 Sn 掺杂 CuO 纳米结构的车载无线驾驶员呼吸酒精检测 (IDBAD) 系统。当所提出的系统检测到驾驶员呼出的乙醇痕迹时,它可以发出警报,然后阻止汽车启动,并将汽车的位置发送到移动电话。该系统中使用的传感器是双面微加热器集成的基于 Sn 掺杂 CuO 纳米结构的电阻式乙醇气体传感器。合成了原始和 Sn 掺杂的 CuO 纳米结构作为传感材料。微加热器通过施加电压进行校准以提供所需的温度。结果表明,通过在 CuO 纳米结构中掺杂 Sn,传感器性能可以得到显著提高。所提出的气体传感器具有快速的响应,良好的重复性以及良好的选择性,使其适合于实际应用,例如所提出的系统。
