It uses an A4-size piece of piezoelectric film in a T-shirt to absorb pressure from sound waves. It converts these into an electrical charge, which it then transfers from its battery into a lead that fits most phones.
它的內(nèi)部置有一張A4大小的壓電式薄膜，可以從聲波中吸收一定的壓強(qiáng)。這些壓強(qiáng)被壓成電流輸出，通過專門的充電線，電流從T恤內(nèi)部的蓄電池中轉(zhuǎn)入到各種型號的手機(jī)電池中。
