Not only in Bangladesh, electricity shortage is a global problem. This problem cannot be solved by the production of electricity in any way. Its impact on the environment has to think first.

Researches are conducting all over the world for environment friendly electricity production. Young people of our country does not lagging behind. Four students of Electrical and Electronic Engineering Department of American International University of Bangladesh (AIUB) have invented a method that produces electricity from the pressure, which is known as Piezoelectricity.

This renewable electricity will be generated when the pedestrian walks, if the machine installed on the floor or on the ground of a crowded area. Project leader Mohammad Habibur Rahman told the details.

We already have Smartphone, tablets; it does not take much time to come wearable technology in hands for different purposes. The comfort of humankind is the root of everything. Demand for these devices is increasing day by day.

Habibur Rahman said, "These devices are running with less power. We have started the production of electricity by thinking of those devices. A large number of people travel on the Farmgate foot over bridge. It is possible to produce a good amount of power if the device can be placed at each step of the stairs.

They have made a square structure with the material that we can get near the hands. There are several parts in the machine. 12 Piezoelectric sensors are placed in parallel format in the three parts of wooden board.

The electricity generated by this machine will be stored in a battery after converted in the DC voltage that suitable for battery saving. This power can be utilized in a variety of works from the battery. The inverter can convert DC voltage to AC voltage if needed. Nabibur Rahman showed the lightening a bulb from generating power.

The most important thing is, this machine can be made by low cost. It will cost Tk. 1800 to 200 for per square foot and will produce 3.18 kWh of electricity in one week. Though seemingly less electricity production, but can be increased by placing a large area. Habibur Rahman said, not the alternative of main electricity, it can be placed as the subsidiary.

Amirul Islam, Abu Saleh Abir and Mohammad Ashraful Alam were in the team of Habibur Rahman to create research paper under the supervision of Assistant Professor of Electrical and Electronic Engineering department of AIUB, Habib Muhammad Nazir Ahmed. They all are in the same department.

Electricity can be generated by putting these devices under the droplets of rain, tracks of rail line, shoe sole, or in the car tires. Inventors of this machine want to continue their research on Piezoelectricity by entering in job life. They wanted to reduce the electricity shortage of the country.
