A team of researchers at Johannes Kepler University Linz in Austria recently developed an image capture device that uses only a single layer of polymer, is flat, transparent, and very soft and flexible. Researchers say it can be used in digital cameras, medical scans, and even the next generation of gesture-controlled smartphones, tablets, and TVs.
The single-layer polymer used in this device looks like an ordinary plastic film, but in fact it uses fluorescent particles to capture incoming light, and then transmits part of the light to a group of sensors on its side. There are no other components or visible electronic components inside. Researchers say it is ideal for future devices that rely on gesture control instead of touch control.
This polymer film is called a fluorescent concentrator (luminescent concentrator), is the basic component of this image capture device. The surface of its sensor is coated with tiny fluorescent particles, which can absorb light of a specific wavelength, and then re-emit it at a longer wavelength. Although most of the light "passes through the hall", a small part is still transmitted to the edge of the film. This allows the set of optical sensors on the outer edge of the film to capture the light and then send the information to the computer. The computer will combine the collected signals to produce an image.
The current pixels are still very low, only 32 x 32 pixels, mainly because of the use of low-cost photodiodes. However, the team is planning to make better prototype products that will reduce the photodiode to achieve a better signal-to-noise ratio. The ultimate goal is to be able to use transparent interfaces for conventional devices, such as TVs or other display technologies. Very attractive prospect!
