Currently under development and it involves a very thin membrane that is foldable and can convert electrical energy into mechanical energy. What do you think it will be used for?
Smaller versions of products that already use this technology. Like motors for example in order to make smaller cars. That would be my guess at least. It seems that all people do anymore is take current and past technologies, convert them into smaller and faster versions then call it it "new and improved".
There is noting new under the sun. Just new versions of the old.
