University researchers have created wearable sensor patches that detect harmful
UV radiation and dangerous, toxic gases such as hydrogen and nitrogen dioxide.
These transparent, flexible electronics – which can be worn
as skin patches or incorporated into clothing - are bringing science fiction
gadgets closer to real life.
Dr Madhu Bhaskaran, project leader and co-leader of the RMIT
Functional Materials and Microsystems Research Group, said the sensors can be
placed on work and safety gear to detect dangerous gases.
“Hydrogen leaks can lead to explosions as happened with the
Hindenburg disaster and nitrogen dioxide is a major contributor to smog,” she
said.
“The ability to monitor such gases in production facilities
and coal-fired power stations gives vital early warning of explosions, while
the ability to sense nitrogen dioxide allows for a constant monitoring of
pollution levels in crowded cities.”
