The joint research team of Kyushu University and Keio University in Japan has successfully developed a sensor that detects the NOx by changing the current value. The researchers used a 10 nm diameter wire to precisely heat the nanoscale space and control the thermal delay time to a sub-microsecond. The test was successful. This technology can be applied to detect volatile chemicals that affect human health. Due to its low energy consumption, it is possible to develop applications for mobile terminals and collect big data on related chemicals, which will create new business opportunities in the future.
In the past, gas sensors have to be heated over a wide range of sensors, and the temperature is as high as 200-300 degrees, so that it cannot be assembled on a plastic substrate, and it is difficult to develop a mobile detecting terminal. The energy required for this technology is extremely low, so there is no problem in assembling it onto a plastic substrate.
This achievement was published on the July 19, 2016 issue of the American Chemical Society's journal ACS Sensors.
