A University of Singapore develops new high-sensitivity graphene sensor

A few days ago, researchers at Nanyang Technological University in Singapore developed a new sensor made of graphene, which is highly sensitive to both visible light and infrared light. The degree is more than a thousand times stronger.

According to reports, the sensitivity of this sensor to light can exceed the imaging sensor used by the camera a thousand times, thanks to the innovative structure it uses. It is made of graphene. Graphene is a super-carbon compound with a honeycomb structure. It is as flexible as rubber and more conductive than silicon. Graphene is a single-atom-thick graphite layer that has gained recognition as a building material for the future.

This new sensor was invented by the Department of Electrical and Electronic Engineering of Nanyang Technological University. The success of this invention can prove that it is possible to make inexpensive and flexible photosensitive sensors using only graphene using existing technology. This innovative invention can have a huge impact not only on consumers of imaging companies, but also on satellite imaging and communications companies. The key to this new sensor is the use of nanostructures that "retain light." Nanostructures can capture light-generating electronic particles longer than traditional sensors. This will result in a stronger electrical signal, just like a photo taken by a digital camera, it can convert this electrical signal into an image.

The sensors of most cameras now use a complementary metal oxide semiconductor as the base. Compared to such metal oxides, graphene bases are much more efficient and can produce clearer and more beautiful photos. Moreover, according to the research and development team of Nanyang Technological University, when designing this new sensor, even the current manufacturing specifications have been taken into consideration. Generally speaking, camera manufacturers can use the same process to manufacture this sensor, only need to convert the base material into graphene. If a company adopts this design, it can bring cheaper, lighter and longer battery life camera equipment.
