Karachi students develop tiles that generate electricity when you walk
Students from Iqra University Karachi made this interesting product.
- Three Karachi students from Iqra University made this invention.
- It is not a new invention but first of its kind made locally in Pakistan.
- The device converts kinetic energy into electricity and according to the students.
- The tiles are installed in an area of 300 meters, they can generate enough electricity to charge 7 to 8 batteries of UPS in just 2 hours.
Karachi students from Iqra University, port city campus have developed electricity generating tiles. The product actualizes a concept of energy harvesting using wood and artificial glass, as it produces electricity when you walk on it.
According to the students, it converts kinetic energy into electricity. The students claim that if the tiles are installed in an area of 300 meters, they can generate enough electricity to charge 7 to 8 batteries of UPS in just 2 hours.
The similar projects have been done in foreign countries before. A similar one is Solar City project by Elon Musk which integrates solar panels within roof tiles to generate electricity. Similar projects will lead to implementation of smart cities on a global level and generate energy through sustainable means.
How does it work?
The Karachi students Ghalib Nadeem, Hafiz Waleed, and Ali Akbar, have managed to generate electricity by using a piezoelectric sensor utilizing crystals. When pressure is applied on the crystals, they produce electricity. A piezoelectric sensor is used to measure the change in acceleration, pressure, temperature or strain, etc.
One of the students who worked on the device, Ghalib Nadeem said,
All people have to do is walk on the grass and it would automatically make electricity. If we walk on it for five to seven hours, a phone’s battery could be charged.
According to the students, the tiles require minimum maintenance. They can be used for up to 4 years if there is there is no water seepage. The product has been developed over the course of 3.5 years and is manufactured using all locally available materials.
The research work and manufacturing cost around Rs. 120,000. The cost can further be reduced if the product is manufactured on a larger scale. The students and their mentor are currently in talks with industry professionals and interested parties.
