Think out of the box. This is what 15-year-old Sarojini Mahajan from New Delhi realized after her idea of using human pulse to charge a cell phone was picked up by Stanford University.

Sarojini, a class IX student of St. Mark’s Senior Secondary Public School, New Delhi, had sent her idea as an entry to IGNITE 2009, a nationwide contest of innovative ideas. Though she won a consolation prize in the contest, Stanford University has decided to work on her idea.

When Sarojini heard the news she couldn’t believe it and said, “I had thought of this idea last year but never told anyone till Neena ma’am once asked for crazy ideas in the class. It was just an idea, which has become so big now.” Sarojini recalled that once she was just sitting and thinking about watches that run on the human pulse and the idea about the possibility of charging mobiles using human pulse suddenly occurred to her.” Neena Punj is Sarojini’s teacher and guide.

Sarojini teamed up with her teacher to develop her idea further who then decided to send her entry to IGNITE this year. They both worked for nearly four months and conceived a charging system in which sensors would be placed on the cell phone. Holding it in hand in a particular way would charge it using the heat of the palm. Sarojini’s recognition has got other students thinking too.

Anjali Agarwal, Principal of the School says, “Sarojini has been a topper in class and though she loves science, she neither wants to become an engineer nor a doctor.” “I may become a scientist but I haven’t decided yet,” said Sarojini.
