British Invention Uses Sound Energy to Charge Mobile Phones

Leading Word: Orange, a British company, invented a T-shirt that uses sound energy to charge mobile phones. The more noisy the user is in the environment, the faster the charging.

The thin film on the T-shirt converts sound energy into electricity.

This rechargeable T-shirt is affixed with an A4 paper-sized piezoelectric film that absorbs the pressure in the sound wave and converts it into electrical energy. Its charger can adapt to most mobile phones.

In addition, some scientists are developing technologies that directly charge sounds for mobile phone batteries. The mobile phone users who like to “push the phone porridge” do not need to worry that the mobile phone will soon be out of power, but will also charge the mobile phone battery continuously, and the louder the sound, the faster the charging.
