As society pushes the boundaries of its sensing capabilities graphene has a large part to play. Graphene’s large surface area, high electrical conductivity, unique optical properties and high thermal conductivity make it ideal for sensors. Ultra-sensitive graphene-based sensors can also be smaller, lighter and less expensive than traditional sensors. Graphene sensors can be used in a variety of different ways; from chemical based gas, pH and environment contamination sensors, through to pressure and strain sensors.
The biological compatibility of graphene also sees it being used in biological sensors capable of sensing molecules such as DNA and many different analytes, like glucose, glutamate, cholesterol, haemoglobin. Graphene sensors might enhance our lives, from the creation of smart food packaging that can monitor suitability of food for human consumption, through to wearable sensors that can monitor health in real time.
