Think of a helmet that will allow the two-wheeler to move only if the rider wears it. Sounds like Aladdin’s magic lamp when authorities are struggling with a situation where most bikers zoom through the roads without one and throwing caution to the winds?

A student of the Nadia campus of Netaji Open university and a teacher of a school have emerged as unlikely champions of the chief minister’s campaign for safe driving by developing such a helmet for two-wheeler riders. If the rider starts the bike without wearing the helmet, the bike will stop automatically.

The trick has been achieved by installing a radio transmitter in the helmet and a receiver in the spark plug of the bike. The former will constantly emit signals and the latter will receive them. The transmitter will start emitting signals as soon as the biker wears it, and will stop as soon as he takes it off.

This wonder helmet was developed by Souren Bhattacharjee and his student Ayan Biswas. Bhattacharjee joined as a teacher at Chakdaha Bapuji High School in Nadia in 2006. Ayan Biswas is a class 12 student of science stream in this school.

The duo hopes to catch the attention of the authorities and the chief minister in particular. Recently, Mamata Banerjee spoke out against the growing trend of two wheeler riders racing on the city roads and not using helmets. Under her instructions, police and oil marketing companies have directed the petrol pumps not to sell fuel to any two wheeler where the rider comes without a helmet.

Explaining the mechanism behind the innovation, Bhattacharjee said, “There is a transmitter in the helmet. When one wears it, it will be switched on generating radio pulse constantly. A receiver fixed with the spark plug of the bike will receive the pulse, and start the engine.”

The implication is clear: the moment the helmet is taken off, the circuit will break and the engine will stop.

If one goes for this helmet, he will have to install a small receiver at the spark plug of his bike. They also claimed to have found out that the continuous emission of these waves from the helmet is not detrimental to the rider’s health.

Bhattacharjee has already led a number of students of his school to various state and national level science fairs and competitions. His students will attend the National Science Meet this year too.

Bhattacharjee recently mailed a letter to the chief minister. He is going to send a letter to her office detailing their innovation again.

“I soon will write to our CM to get help and cooperation to bring it for the help of common people,” he said.

Both student and teacher appeared bubbling with enthusiasm, excited their device can, at least in theory, bring down the number of two-wheeler accidents.

They told HT the device cost will be around Rs 250 only. They have taken about one year to develop the helmet.

Bhattacharjee studied physics in Shantipur College in Nadia district. While he was a student of part I, got the job in Air Force and was posted in Pune.

There he graduated in arts, and later obtained a post graduate degree in history and environmental science gradually from Netaji Subhas Open University.
