Novel Fluorescent Finger Print Monitoring System for Car Drivers and Passengers

Road crash is major risk in automobile sectors. Drugged and drunken drivers are major cause for this crash. As per published report in National institute of Drug Abuse 2019, more than 20 million drunken drivers or drugged drivers are lost their lives. These drivers can be classified as high risk drivers putting their lives in risk but also others such as pedestrians and passengers. The main focus of this work is to develop the alert system that can give real time data of alcohol or cocaine level in sweat and exhaled breath of drunken/drugged drivers and prohibiting them to drive the vehicles. Here novel fluorescence boron nitrogen co doped carbon quantum dots sensors are developed with high selectivity of alcohol and cocaine in breath as well as sweat. With only fluorescence boron nitrogen co doped carbon quantum dots, the senor could quantitatively simultaneously detection alcohol (4–235 μM) and (10–395 μM) cocaine in exhaled breath. The developed sensor shows high sensitivity in the range of 0.22
${\mu AmM-^{1}\,cm^{2}}$
range with 95% confidence limits. These sensors are flexible, mechanically stable and easily integrated on steering, seat belts and car cabinets. The sensors response time is less than 60 secs and have capability to monitor drunken/drugged driver physiology and prevent the access of vehicles. Deviation of fluorescence is directly related to level of alcohol and cocaine in sweat and exhaled breath. The output signals of sensor decide and grant permission to drivers to drive or not to drive. Thus implementing this sensors in autonomous vehicles safe person life and prevent the damage of public properties.
