Everyday changing diapers of kids becomes a pressing concern for parents. It is complicated, costly and causes diaper rashes to babies. What if new equipment can be developed with a sense of clairvoyance, which can tell parents beforehand that their kids are going to pee? It can ease the burden of parents and can also save their money. It seems a dream, but has been made possible by group of three engineering students of University of Kashmir along with their guide.

Jahangeer Aurshad Bhat of Bandipora, Ejaz Ahmad Bhat of Pattan and Mansoor Ahmad Bhat of Baramulla, who have completed BTech in electronics and communication this year from KU’s main campus, under the guidance of their guide Rouf-Ul-Alam Bhat, have developed prototype of a diaper that foretells parents when their kid is going to pee.

The idea struck Jahangeer’s mind, when he visited one of his friend’s home and saw his paralytic father waggling awkwardly on his bed. When he inquired about the issue, Jahangeer found that paralytic man is actually feeling it discomfiting to tell his family in front of guest that he needed to urinate. “When I saw the condition of friend’s father, I was pained. Later, I thought of developing an equipment that would help patients like him to communicate with their family members in case they want to urinate,” says Jahangeer.

Next day Jahangeer discussed idea with his teacher Rouf and his friends Ejaz and Mansoor. “When Jahangeer explained the idea to me, I found it interesting and we started working on it,” says Rouf.

“We developed this diaper for adults first like paralysed, mentally challenged and old-aged people, later we thought to lessen the burden of mothers, who change three to four diapers daily of their kids. It affects them financially and physically,” says Jahangeer.

“Besides daily use diapers have a presence of polyvinyl Chloride causes rashes to new born babies. Some studies have also revealed that these diapers grow a larva, which can later cause infertility in female children wearing these diapers. Our product can prevent kids from such diseases,” ads Jahangeer.

All four innovators started this project in 2014 and after fabricating their idea, they presented it at Directorate of Scientific Innovation and Research (DSIR). “After finding our idea interesting, DSIR gave us Rs 1.5 lakh as monetary help for our project,” said Jahangeer.

With their effort and hard work these four innovators made a successful prototype in 2017 and gave it a tentative name ‘baby pee sensing and foretelling device’.

To secure a patent to their invention these four innovators have also applied for patent at India Patent office located at Delhi. “We have filed a patent application and received acknowledgement number from Delhi. They have almost approved our patent,” says Mansoor.

“Recently, a Japanese company, Unicharm PVT Ltd, approached us and took a test of the prototype we have prepared. If the company finds our prototype interesting either they have to give us royalty percentage or they will buy patent from us. We will decide that, once they approach us again,” Mansoor adds.

This diaper has three sensors namely Flex based pressure sensor, capacitive sensor and resistive sensor. These sensors work together to detect urinary bladder of child. Once the bladder gets filled, these sensors send signal to processor and processor transmit wireless signal to a person who wears watch that comes with this product through radio frequency. The diaper can also be connected with a mobile phone.

Baby pee sensing and foretelling device is rechargeable. It contains harm free paper battery, which is flexible. The battery of this device needed to charge once in three months. There is no need to worry if sometimes unintentionally kids piddle inside diapers, because these innovators have made this device reusable. “Failure is possible in anything. If anytime by chance kids urinate inside diaper. We can remove it, wash it, wipe it and use it again. There is no need to buy new one,” says Jahangeer.

Besides the diaper has medical use as well. It can test non-invasively the failure of Urethral Sphincters whose function is to control the outlet of urine in the urinary bladder through the urethra and Detrusor Urinae Muscle whose function is to allow bladder to store urine.

Rouf said, as no such type of equipment has been invented before, so this product will have a great demand in the market. It can help parents to prevent their babies from side effect of daily use diapers and can give comfort to those patients who remain bedridden because of serious illness. On an average, parents spend Rs 70 to Rs 80 on diapers of a kid everyday. The baby pee sensing and foretelling device can save the money of parents.
