Today we have wearable fitness trackers, sensors that detect a drop in blood sugar for people with diabetes, and sweat patches to monitor drug use in people on probation. It seems logical to assume that we could also detect the amount of alcohol in our bloodstream without the need for a blood test or traditional breathalyzer. With this type of technology, individuals could monitor their blood alcohol content (BAC) prior to getting behind the wheel to determine if they are under the legal limit. But it would also law enforcement to monitor individuals with OUI convictions. If you’ve been charged with OUI, contact a Boston defense attorney today.
Less Embarrassing Than an IID
If you are convicted of OUI, you may be permitted to continue driving with the installation of an ignition interlock device (IID). By blowing into the device, you allow the system to measure your BAC; if alcohol is detected, the engine won’t start. Unfortunately, IIDs are expensive to install (a cost the offender must absorb), and they can be embarrassing. Can you imagine a first date where you have to blow into a device to start your car after dinner? For these reasons, as well as to allow individuals to check their BAC before getting behind the wheel, engineers have been working on a more efficient method of detection.
Researchers from the University of California San Diego have developed a wearable device that can effectively measure BAC. The “temporary tattoo” adheres to the skin, induces sweat production, measures the individual’s BAC, and sends that data to a smartphone, laptop, or IID, eliminating the need to blow into a device to start your car. The alcohol sensor communicates the information via Bluetooth. Although BAC is most accurately measured with blood tests, breath and perspiration also provide reliable results. Sweat-reliant devices have been in the works for years, but they haven’t been particularly reliable until now. There was a dangerous delay in results; it could take hours for the sweat’s measurements to match the actual BAC. That problems has been resolved; the new sensor can “accurately monitor alcohol level in sweat within 15 minutes.” Contact a Massachusetts OUI lawyer today.
Sweat Sensors May Allow Drinkers to Self-Monitor
In addition to providing an alternative to IIDs, PhD Student Jayoung Kim, one of the sensor’s creators, hopes that it can help drinkers monitor their ability to drive safely. “”When you’re out at a party or at a bar,” said Kim, “this sensor could send alerts to your phone to let you know how much you’ve been drinking.” Beyond self-monitoring and allowing those convicted of OUIs to resume driving, sweat patches may also one day be used to monitor a person’s BAC even when not driving. This could be useful in certain situations, such as probation cases, but certainly has the potential to be highly invasive. Then again, information sharing, across the board, has been moving in that direction. From social media to face scanning software, the idea of privacy has been undergoing a significant shift in recent years, for better or for worse. Continue reading
