Qurv Technologies, a Spain-based startup established in 2020 to develop wide-spectrum image sensors based on graphene and quantum-dot technologies, has developed a sensor that combines the unique electronic properties of graphene with suitable quantum nanoparticles as light sensitizers. The new device reportedly enables efficient detection of a broad range of wavelengths – from ultraviolet to infrared light – all concentrated into one simple device.
The production and transfer process of graphene leverages existing scalable Complementary Metal Oxide Semiconductor (CMOS) manufacturing processes. Furthermore, this graphene-based sensor could replace traditional costly alternatives based on indium gallium arsenide, paving the way to SWIR imagers up to 1000 times cheaper.
Graphene-based wide-spectrum sensors could boost machines' 'sight' and decision-making capabilities. Computer vision applications are useful in a variety of fields, from autonomous cars – capable of detecting obstacles around them – to intelligent machineries such as service and industrial robots. Qurv has created a "plug-and-play" manufacturing approach, making it more widely compatible and accessible than curre
