Graphene-based Magnetoresistance Sensor 200 Times as Sensitive as Silicon
Abstract:
Most of the sensor chips that turn home appliances such as refrigerators and washing machines into smart devices do so by detecting changes in electrical resistance brought on by the presence of magnetic field—also known as magnetoresistance (MR). These sensor chips, sometimes referred to as MR sensors, have traditionally been fabricated from silicon.
Now researchers at the National University of Singapore (NUS) have produced these MR sensor chips out of graphene and boron nitride. Their version is 200 times as sensitive to electrical resistance as its silicon counterpart.
