This smart ring god can detect chemical threats

Wearable devices are changing the world. According to a recent report by the US Daily Science website, in addition to designing fashion and being able to track heart rate and other physiological indicators, UC researchers released the latest report showing that wearable sensors can also be used for testing. The threat outside the body, for which they designed a ring that can detect chemical threats such as explosives.

According to reports, Joseph Wang of the University of California, San Diego, and colleagues wanted to develop an economical and portable wearable sensor to detect the threat of external chemicals. The team designed the sensor as a ring that can be worn on a finger.

The ring consists of two parts, an electrochemical sensor cap for detecting specific compounds and a circuit board that processes the data and wirelessly transmits it to a smartphone or laptop.

It performs voltammetric and chronoamperometric measurements with a high degree of selectivity and sensitivity, which allows the ring to detect a wide range of chemical threats. In the current prototype form, it is optimized to detect explosives and organophosphate neurotoxins. Researchers say the device can be extended to other hazardous environments.

The researchers said: "We have demonstrated for the first time a fully integrated ring based on a variety of chemical sensor platforms that can be used to simultaneously monitor several (explosive and neurotoxin) security threats. The current work also addresses the growing demand for fashion and The combination of the advantages of the wearable field has created wearable accessories for the widespread acceptance of wearable sensor technology ."

According to the global analysis company "CCS Insight", by 2020, the market for wearable electronics will reach $34 billion. The wearable products currently being developed include tattoos, masks, wristbands and headbands. The sensors used in all these devices are also facing certain challenges. The sensors in the industry are economical, compact and non-invasive to users. Easy to use, but for now, more advanced sensors are expensive and difficult to produce. For example, a sweat sensor worn on the arm requires the user to generate enough sweat to make the device work properly, which is a current situation.
