Nokia has always been the king of mobile imaging and seem like they will be not counting on the yet to be announced Lumia EOS to keep them there. A patent was filed by Nokia last month for using Graphene in their image sensors. Why would you use Graphene you ask? Simple Graphene is 1000 times more sensitive to light than normal camera sensor plus it would take a lot less room in the device itself.
In case my nutshell summary of this technology wasn’t good enough for you here it is in technical jargon:
In accordance with an example embodiment of the present invention, an apparatus is provided, including a plurality of photon sensing layers arranged on top of each other, and an intermediate layer between each two adjacent sensing layers, the sensing layers being of graphene, and each intermediate layer being configured to prevent a respective color component of light from proceeding into the photon sensing layer next to it.
In an example embodiment, there is provided a camera sensor based on graphene photo detectors. In an example embodiment a graphene transistor is used to detect photons. The detector may be integrated to a camera sensor system which functions similarly as a CMOS sensor, or like a CCD sensor, or similar. In an example embodiment, it has been observed that the photon detection ability of graphene can be used to separate different wavelengths with the use of suitable intermediate filtering layers, and the structure can be used as a camera sensor.
In an example embodiment, the apparatus is a handheld mobile communication device, such as a mobile phone. In an example embodiment, the apparatus is a digital camera. In certain embodiments, the apparatus is a digital storage camera, mobile phone camera, a security camera, or an embedded camera structure.
