Researchers at Japan Advanced Institute of Science and Technology (JAIST) and Otowa Electric, a lightning protection equipment manufacturer, have used graphene as an electric field sensor that can detect both positive and negative electric fields.
The response of the sensor is recorded as the change in drain current under the application of an electric field. In addition, by systematic analysis, The team established the mechanism of the graphene electric field sensor, which was found to be different from what they expected.
