From micro smartphone projectors to paper speakers

Brighter, smarter and thinner; that’s how scientists in Germany describe the new type of projector they have developed.

Based at the Fraunhofer Institute in Jena, they are hoping the technology will become standard in smartphones in the near future.

Scientists drew inspiration from nature, from the eyes of insects. Each device consists of hundreds of tiny micro projectors and each projector generates a complete image.

Staying in Germany, at the Chemnitz University of Technology, researchers have developed what they say are the world’s first printed paper speakers.

They are hoping their technology – which produces a surprisingly good quality sound – will be used in a variety of ways – posters, talking packaging and even a newspaper which reads to you.
