Some bracelets and smart watch products have been approved for lack of practical functions. After the user has been fresh, the wearable products are shelved. According to foreign media reports such as Reuters, a US startup has introduced a bracelet that can measure the body's alcohol content, which will help improve driving safety or improve health monitoring. It is reported that the National Institutes of Health held a "wearable biosensor challenge contest". Recently, a bracelet that can measure alcohol in the body won the first place and took away the $200,000 prize. Called "BACTrack Skyn", this bracelet is designed to analyze the amount of alcohol in the blood through sweat. Since the data is obtained through the skin rather than directly through the blood, there is a certain hysteresis in the body alcohol content measured by the bracelet, and the body's alcohol is emitted through the skin sweat, and the drinking time is about 45 minutes. This bracelet is currently only a prototype product, and there will be room for improvement in the future. In addition, the bracelet will be connected to the smartphone to present measurement data via a mobile phone software. The developer of the bracelet said that the bracelet is not a substitute for the current respiratory alcohol measuring device used by the police, but the product can provide the user's recent record of alcohol content in the body. An expert from the National Institutes of Health said that in medical use scenarios, doctors can monitor the recent alcohol content of a patient based on the record of the bracelet and understand his drinking situation. It can play a role in the field of treatment of alcoholics. In this challenge competition, there are also several bracelet products that measure alcohol content. One of the bracelets can form a “temporary tattoo†on the skin to measure the body's alcohol level according to the color change. In the bracelet and smart watch market, measuring body health data through various biosensors has become an important area. In the past, wearable devices focused on physical indicators related to exercise and fitness. Today, there are many advanced sensors that can measure more data such as the amount of substances in the body. For example, a Russian company launched a bracelet that measures blood sugar levels in a non-invasive condition.
