According to foreign media reports, a research team from the Chemnitz University of Technology in Germany recently announced that they have developed a revolutionary new technology that can use special paper to turn printer ink into a pleasant sound.
It is reported that the paper consists of a multilayer conductive organic polymer and a piezoelectric sensing layer. After the ink is printed on it, it can start working as a speaker. If you are worried that the sound is not big enough, you can connect an amplifier to increase the volume. Researchers say the frequency response and sound quality of this paper speaker are quite good.
If such a new technology can be put into use, there is no doubt that its commercial potential is very large. Maybe soon, we will be able to see the posters that will speak.
With Push-in connection technology, you can connect conductors easily – both directly and without tools, insert forces reduced by 50%. it is suitable for various applications. Insert rigid conductors or conductors with ferrules from 0.25mm² into the conductor shaft.The contact spring opens automatically and provides the required pressure force against the current bar.
When installing smaller conductors from 0.14mm², use a standard screwdriver to push the orange button and actuate the contact spring.
Push-in Connection have test and passed various certificates. For example, Vibration resistance in accordance with railway standard DINEN50155,shock and corrosion resistance in accordance with current shipbuilding registers.
