Technology developer InVisage Technologies has announced sensors it says can offer four times better performance than conventional CCD and CMOS sensors. The company's 'QuantumFilm' technology uses the unique electronic behavior of quantum dots (precisely-sized nano-scale crystals trapped in a polymer film) to replace conventional silicon photodiodes. The company says the quantum dots themselves are twice as sensitive to light as conventional photodiodes and that their placement on the sensor surface offers a further doubling of sensitivity over front-illuminated CMOS designs. The film can be positioned on conventional circuitry, allowing the chips to be produced more cheaply than CMOS or CCD designs. The first application will be in mobile phones sensors later this year.
