Scientists in south korea have developed a flexible,foldable and wearable fabric which generate electricity the advance represents an important steps towards making wearable electric sources a reality. Sang woo kim led the developed the material. he worked at sungkyunkwan university in suwon ,south korea,a shirt made from the new fabric can be worn pathed like any other item of clothing.fully equipped its just a tad on the heavyside he acknowledges. that added weight comes grom electronic the researchers wired into the shirt.for testing,this included small screens, lights,keyless remote press the shirts cuff for instance and the remote unlokes a cars door too. The powergenerating material in this clothes is wearable triboelectric nanogenerator . tirboelectricity is electricity generated by friction .the material includes tiny zinc oxide rods onlybillionth of a meter long.those spiky nanoparticles help convrt motion into electricity.some kinds of triboelectricity are familiar.the newfabric combines different materials. Top and bottom layers are clothe coated with silver .middle layer contains the zinc oxide coated with polymer. when the fabric moves the coated rods move back and front against clothes. the movement produces a reaction.the polymor layer that picks up electrons from the silver layer.the research connected the two outer siliver layers with wire .the wire lets a small electric current run through it. Multiple layers of wearable triboelectric nanogenerator producedmre electricity than single layer.the smart shirt generated enough electricity to power a small sereen. it glowed too.the shirt also lighted up an array of small light emitting diodes.and it powered the kkeyless remote.the is only works when some one is moving.
