Scientists using elegant technologies have discovered a technique to recharge smartphones using fingers.
The biggest problems in the smartphones are that the batteries get drained. In order to resolve this, Scientist from Pennsylvania State University have claimed to have developed a device made out of an organic polymer that converts the mechanical energy from touching a smartphone screen or when a raindrop falls on it into electricity, using a new energy harvesting concept.
The device, known as an ionic diode, contains two electrodes filled with ions almost like batteries.
When a mechanical force is applied, the ions spread out on the membrane, creating a continuous direct current that imparts microwatts of power to the main battery.
