Researchers crack the long-standing problem of how to make stretchy batteries to power a growing range of stretchy electronics.
'The team says the stretchy battery can be charged "inductively" - that is, wirelessly over a short distance. Prof Rogers said that the uses for such batteries and the stretchy circuits they power were myriad.
"The most important applications will be those that involve devices integrated with the outside of the body, on the skin, for health, wellness and performance monitoring," he explained.
However, the prototype batteries described in the paper were only run through 20 charge/discharge cycles, and Prof Rogers said that "additional development efforts to improve the lifetime will be required for commercialisation".'
