Put on this dress, the smartphone will never be powered

The latest researchers from South Korea and Australia say that there will be a soft and durable rechargeable clothing in the future. It can charge a wearable device by collecting static electricity caused by human activity.

Wearable devices like the Apple Watch that consume fast electrodes will gradually emerge in the future, but the battery makes these novel gadgets extremely limited. Despite being bendable, the stretchable battery can get rid of the battery shape limitation, but the battery power and service life have not been solved.

The newly developed energy garment is said to use a natural phenomenon called triboelectric. When two objects rub against each other quickly, one object will steal electrons from the surface of another object. This is why the static electricity is generated when walking on the ground.

The soft and foldable power-generating material consists of two fabrics, the first being silver-plated and the second consisting of silicone rubber, zinc oxide nanorods and silver.

When the researchers used to stack four pieces of fabric and rubbed them quickly, the voltage instantly rose to 170 volts, while the current reached an average of 120 microamps, and the highest power reached about 1.1 kilowatts. This dress is very durable, because it takes 12,000 compression release cycles to generate electricity.
