# Pupil-Measuring Breathalyzer Alternatives A 7th Grader Created This Impaired Driving Drug-Detector By Cadhla Gray | Published 2015-10-07 | Autos Source: Trend Hunter, https://www.trendhunter.com/trends/impaired-driving References: [youngscientistchallenge](http://www.youngscientistchallenge.com/contests/entry/18936) & [businessinsider.my](http://www.businessinsider.my/3m-young-scientist-challenge-reddy-2015-10/) While breathalyzers already exist to test for impaired driving, they can only detect alcohol consumption, overlooking the possibility that someone has taken drugs. A 13 year old boy from Texas, Krishna Reddy, discovered a way to solve this problem by designing a device that measures potential drivers' [pupil dilation](https://www.trendhunter.com/trends/ocular-diagnostics). The device uses a camera, toilet paper roll and flashlight. It functions by shining a flashlight, directing it into someone's pupil with the toilet paper roll, all while a camera records the pupil's movement. This movement is then analyzed using an app that [measures the size of constriction](https://www.trendhunter.com/trends/ai-optics). It not only [detects alcohol, marijuana and amphetamines](https://www.trendhunter.com/trends/drug-screening-system), but boasts an intelligent design that doesn't necessarily require a person's consent. The future development of this test for impaired driving could even be integrated into a rear-view mirror in order to start a car. ## Trend Insights (Trend Hunter) - Score: 1.1/10 - Popularity: 5% | Activity: 20% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Gen Z, Millennial, Gen X - Top markets: North America, Europe ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Autos](https://www.trendhunter.com/autos) ## Key Themes ### What Makes This Trend Stand Out - **Multi-drug Breathalyzers:** Innovation opportunity for companies to develop breathalyzers that can detect multiple drugs to improve road safety. - **DIY Medical Diagnosis:** Companies could explore developing simple and affordable DIY medical diagnosis tools for consumers. - **Innovative Youth Inventions:** More companies should focus on supporting and investing in innovative youth inventions that have the potential to disrupt existing markets. ### Sectors Adopting This - **Automotive Industry:** Automakers can consider integrating Krishna's device into their cars to improve safety. - **Healthcare Industry:** The healthcare industry could adopt the use of similar DIY diagnostic tools to improve patient access and reduce costs. - **Consumer Electronics Industry:** Companies in the consumer electronics industry can explore developing low-cost and effective devices for measuring different biometric data for health and wellness. ## Related on Trend Hunter - [Alcohol-Monitoring Bracelets](https://www.trendhunter.com/trends/alcoholmonitoring-bracelet.md) - [Drunk Driving Detection Tools](https://www.trendhunter.com/trends/drunk-driving-detection.md) - [Workplace-Focused Alcohol Breathalyzers](https://www.trendhunter.com/trends/alcohol-breathalyzers.md) - [Intoxication-Indicating AI Technology](https://www.trendhunter.com/trends/drunkdriving-detection.md) - [Virus-Detecting Breathalyzers](https://www.trendhunter.com/trends/virusdetecting-breathalyzer.md) - [Drug-Detecting Drink Strips](https://www.trendhunter.com/trends/greenlane.md) - [Portable Methanol Analytical Devices](https://www.trendhunter.com/trends/analytical-device.md) - [Revolutionary Alcohol Detection Software](https://www.trendhunter.com/trends/alcohol-detection-software.md) - [Noninvasive Breathing Trackers](https://www.trendhunter.com/trends/home-breath-analysis.md)
