The unique properties of graphene mean that it will have a huge impact on electronics. One example is in semiconductors, where the thinness and conductivity of graphene give it the potential to replace existing technology for computer chips.
One of Paragraf’s technologies is graphene-based Hall sensors, which measure fluctuations in magnetic fields. Sensors like these are common in cars where they measure current by sensing fluctuations in magnetic fields, but Paragraf is the only company whose product is a graphene-based electronic device.
NPL investigated performance of the sensors in extreme environments, including at high temperatures, at high frequencies and when exposed to radiation. The results were extremely valuable, giving an insight into internal reconfiguration that led to the electric vehicle battery usage and revealing new applications for the sensors in turbines and space technologies.
