Another innovator to meet the President was Akash Manoj,

a 15-year-old student from Tamil Nadu, who has invented a device to predict silent heart attack.

Silent heart attacks, which have a little or no symptoms, are alarmingly common and extremely deadly. Currently, there is no way to detect a silent heart attack.

Once Manoj's grandfather collapsed due to a heart attack, he decided to find a solution to this problem.

He then contacted the National Innovation Foundation (NIF) and began work on his device.

His device sticks to a person's wrist or back of the ear which can be used to monitor whether there has been a heart attack. His technique is currently undergoing clinical trials.

The other innovators include Surjeet Singh who helps farmers produce high quality basmati rice. Moa Subong from Nagaland invented a musical instrument made from Bamboo. Ajay Kumar Sharma has prepared a farmer-friendly compressor for biogas bottling. Girish Badragond from Karnataka has invented a device to detect water availability in a particular area.

Mansukhbhai Prajapati from Gujarat has invented clay refrigerators which run without electricity and clay kitchen utensils. Subhash Ola from Rajasthan has prepared energy-efficient milk boiler for industries.

Paresh Panchal from Ahmedabad has prepared a machine which helps prepare Agarbatti (incense sticks) in large scale.

Santosh Pachar from Sikar in Rajasthan has invented an improved variety of carrots.
