Living in major cities and going outside of your home comes air pollution that can harm our body and health.
But what extremely harmful to health is indoor pollution which has been more of a concern that led to sick building syndrome, sick car syndrome, and sick school syndrome.
Scientists from University of Southampton and Japan Advanced Institute of Science and Technology (JAIST) have created a lightweight sensor that can detect indoor air pollution.
The switch and sensor made from graphene is a one-atom thick and is super durable and the device operates with a very little power consumption. It works by detecting volatile organic compounds and individual CO2 molecules that are lingering indoors.
Because CO2 and VOCs are found in extremely minuscule concentrations (parts per billions), its hard to detect with technology that’s only parts per million.
The research team believes that if they can both integrate the sensor and switch, it will create a super low-powered environmental sensor that works at similar efficiency.
“In contrast to the commercially available environmental monitoring tools, this extreme sensing technology enables us to realize significant miniaturization, resulting in weight and cost reduction in addition to the remarkable improvement in the detection limit from the ppm levels to the ppb levels,” stated Professor Hiroshi Mizuta.
