An updated pH sensor thinner than a human hair has been developed using nanotechnology to replace traditional glass electrode devices, which have been in use since the 1930s.
Scientists used a magnetron sputtering system to precisely produce a layer of ruthenium oxide 500 times thinner than human hair.
The sensors can be miniaturised and cheaply mass produced, leading to exciting new applications in the oil, gas and medical industries.
