Raincoat for your cellphone

We were thinking about informing the authorities and ask them to look for it when one of us said, "What's the use? The SIM card and the handset is probably too damaged by now."

The incident left him with a depression for two days and one and a half weeks without a cellphone.

But I can bet my buddy would definitely use "the internal water-proof coating" on his future cellphones to safeguard them from water damage.

Anwar Shahadat Angur a multiple national award-winning scientist invented the coating.

"This coating consists of a layer of special material which protects the circuit-board of a phone from oxide gases and water. The material will melt at a temperature of 150 degrees centigrade and is a bad conductor of heat and electricity," said Angur.

He explained these properties of the coating would bar water from entering the circuit-board which can otherwise cause problems in the innermost hardware and delicate software of the cellphone.

While charging a cellphone a substantial amount of oxide gases are discharged. This causes the internal hardware of the phone to rust. The rust causes short circuit and other problems within the wirings and circuits.

"The phone gradually decays due to this reason but the internal coating will prevent the internal hardware, wiring and other connections from rusting," claimed Angur.

The coating will also protect the circuit-board from heat caused by excessive use and other damages.

In case of repair or addition to the set, the coating would need to be heated at 150 degrees centigrade.

"This can be done quite easily with a soldering iron. The coating can again be laminated after the necessary changes have been made," said Angur.

The coating is currently available at Angur's Texman Bangladesh shop at Fakirapul.

Anwar Shahadat Angur, from the remote district Sherpur, has already made a name for himself as a scientist. He has received nine awards from various private and national organisations since 1991.
