Researchers have designed a sensor that can be worn as a ring and can detect the presence of a wide array of harmful chemical and biological substances, including explosives and highly toxic nerve agents.
In a breakthrough against terrorism, Joseph Wang and his colleagues from the University of California say the wearable device shows considerable promise for meeting the demands of a wide range of defence and security scenarios.
With increasing terrorist threats and political instability, there are urgent needs for developing wearable sensing platforms for detecting chemical and biological threats,” the researchers said.
In future, the ring-based sensor could also be modified for use in other areas, for example, in industries which deal with hazardous chemicals.
