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.
Graphene for IOT and sensors
See what graphene can do for IoT and sensors! Highlights from the Graphene Flagship exhibition at Mobile World Congress 2017 includes solutions showing how graphene can be used to enable a higher level of connectivity, ranging from smart homes and self-driving cars to monitoring dangerous chemicals.
The latest on sensors
We interview Peter Steeneken (above) about the advantages of graphene and related materials in the development of sensing devices – particularly NEMS.
Cheap and efficient NO₂ sensors measure changes in graphene’s electrical resistance to record pollutant levels – and they could be strung together to create real-time pollution maps of cities.
Dubbed as the 'year of wearables', 2014 witnessed a surge in wearable technology for health applications and, since then, the rate at which products are released has not slowed down.
A team of scientists at Graphene Flagship partners have exploited the ultra-thin and highly conductive properties of graphene to develop an extremely small accelerometer with exceptional sensitivity.
The Graphene Flagship launched on 1st October 2013. Six years later, researchers from Graphene Flagship partner Université de Strasbourg, France, developed a graphene-enabled pressure sensor inspired by French famous multi-layered pastry - the 'mille-feuille'.
