Wearable sensor for universal fingerprint detection on bionterfaces

In personalized medicine, wearable sensing technology is an important link, where researchers need to simultaneously monitor several analytes within the body to obtain a full image of human health.

South Korean researchers have successfully created a wearable sensor that can use nanomaterial processing to detect illicit drugs in sweat, amplifying the optical signal of opioids to a flexible, body-worn material.

In order to provide a universal, responsive molecular monitoring method to determine human health, the sensor bridged the gap in wearable sensing technology.

Sweat, which is not invasive and comparatively free from human rights concerns, was the subject of the researchers. However, even though sweat involves several medications ingested, only a limited amount of substances is emitted into sweat, so a highly sensitive sensor technology had to be developed for improved detection.

The devices allow researchers to continuously analyze vital signs, including heart rate, body temperature, transpiration, and physical activity. Non-invasive molecule detection methods that offer insight into human body processes at the molecular level continue to be realized, considering the popularity of physical wearable sensors.

This technology will help solve social issues such as celebrity-related drug trafficking and violence, club drug sales, and athletes’ banned drugs. As the cost of manufacturing is less than 50 cents per item, during major sporting competitions such as the Olympics, it can be used as a full enumeration survey for an anti-doping program.

As seen in recent drug-related crimes, Korea is no longer a drug-free country. The developed technology would overcome the technological limitations on identifying drug and prohibited substance use and enable drug detection without invasive and ethical problems.”
