Triboelectric generators will be able to allow electricity-generated touch screens. The pyramid patterns which are created in polymer sheets will increase the production of the electric current in the latest triboelectric generators.
This is possible because researchers at the Georgia Institute of Technology have used the triboelectric effect. This effect has an electric charge generated by means of friction between two separate materials to develop a generator to supplement power that is produced by the piezoelectric nano-generators which were developed earlier at the Institute. Such generators can be used to create electricity from simple functions like walking to help touch screens to generate their own power.
Now, people can imagine a scenario in the future where tablets and smartphones have extended battery life without the need for a bulky battery. Every time a touch screen will be used, it can generate electricity which can be made to power it. The battery can then be used for powering other internal components. Display is the biggest reason for drained batteries.
The researchers have introduced a gap separation technique which produces a drop in the voltage leading to a flow of current that allows the charge to be used. The generator can transform random mechanical energy from the environment into electrical energy.
In the specified case of triboelectric generation, the generator will generate a charge when polyester sheets giving out electrons will rub against sheets of polydimethylsiloxane (PDMS) that accept electrons. After the friction, the electrons are mechanically separated to create an air gap which isolates the charge on the PDMS surface and forms a division of positive and negative charges. The process of preparation is not very costly and can be done on a large scale for practical applications like touch screens of smartphones and tablets.
