It pulls off this trick by using stretchy polymers, called elastomers, in conjunction with conductive gels, to transport charged particles between the battery's terminals.

这是用一种叫弹性体的聚合物材料制成的，它与一种可导电结合，这种就可以在电池的两端传输带电粒子。

Both of these are aiming for true mobility, retaining the hand-off circuitry and trying to make terminals as small as possible. (They are currently about the size of a videotape, but both firms claim that cards which can fit inside a laptop are coming soon.) In the process, however, they have sacrificed telephony and focused solely on data-only systems.
