Thanks to the commitment of engineers and scientists, today’s batteries are much smaller and manageable than in the past, but in many cases this is not enough. Those placed in accessories to wear are the most common size and shape of a small coin, and although it would seem that there is no such device, in which will not fit, then with the increasing miniaturization of technology are often already too large. In short, we need a breakthrough to fully enjoy the possibilities of modern accessories.
I predict such a breakthrough, researchers from Stanford University, who developed a battery that is soft, flexible and a lot safer than the ones used today. Instead of the adhesive and viscous reached this purpose the polymer retains a more stable form, such as a pencil eraser or rubber band. This is able to store enough energy to power small electronics and at the same time is non-flammable, giving him a big advantage over current solutions.
Presented by scientists prototype is the size of a fingernail on the thumb and store as much energy as conventional batteries. Moreover, it retains its properties even when it is compressed, folded and stretched, and can thus increase almost twice its length! You also can not forget that in this case there is no risk of chemical leakage or explosion, because we are not dealing with the polymer in the form of a gel, as in typical batteries, so accessories to wear with a new type of battery will be much safer.
– Until now we had no energy source that could stretch and bend in such a way to adapt to our body and enable the production of electronic accessories, which are really comfortable to wear – says Zhenan Bao of Stanford University. Now it has to change, and scientists say that one of the most important applications may here be flexible sensors glued to the skin in order to monitor heart rate. Later, while we expect the larger versions of these batteries, which will go to larger devices and will be characterized by greater energy density.
