Shiny blue dye the answer to creating button batteries safer for kids

An “a-ha second” for a Wellington researcher a number of years in the past has resulted in a first-of-its-kind product that would save 1000’s of younger lives across the globe.

Jeongbin​ Okay, a senior lecturer at Victoria College’s Faculty of Design, has created a coating for button batteries which, if positioned within the mouth or swallowed by a baby, leaches food-safe blue dye, permitting for fast detection by a caregiver.

The concept for the know-how got here after Okay seen a younger boy on the road along with his mouth stained purple, after consuming some type of meals.

The commentary shortly set the wheels in movement for the creation of the battery coating, with a major deal with fixing a worldwide downside.

“Battery ingestion is a extremely severe problem … as soon as the battery is positioned, after which swallowed, it is very possible to turn out to be lodged within the oesophagus [where] it begins to burn the encircling tissue and ultimately may cause everlasting accidents or generally dying.”

When the battery is placed in the mouth or swallowed  by a child, the coating leaches food safe blue dye, allowing for quick detection.

When the battery is positioned within the mouth or swallowed by a baby, the coating leaches meals protected blue dye, permitting for fast detection.

At Auckland’s Starship Hospital, battery ingestion causes as much as 20 hospitalisations yearly and, in the USA, it accounts for round 3000 annual hospitalisations.

Button batteries are extremely corrosive and may trigger severe tissue injury and even fatalities inside two hours of ingestion. Nonetheless, Okay mentioned there have been usually no outward indicators little one had swallowed one till it was too late.

His meals colouring-based coating seeks to treatment that, and it is a product that is gaining consideration globally.

Together with Viclink, the college’s commercialisation workplace, Okay is getting set to take the invention to the following stage by partnering with world battery producers.

The product has not too long ago been patented in the USA, European Union and Japan, with extra nations possible.

“I hope to see mass manufacturing of this coating and to see it turn out to be an trade customary,” Okay mentioned.

“It has all the time been my dream to assist save lives, and I hope this coating can play a component in doing so by creating an invention that has world implications for the security of youngsters.”

The coating could be utilized through the manufacturing course of or utilized to current batteries utilizing a pen applicator.

“It is a implausible innovation that is cheap for producers to implement however has monumental potential for public good,” Viclink commercialisation supervisor Liam Sutton mentioned. 


The ham experiment exhibits what can occur to a baby’s insides inside simply hours of swallowing a button battery.

“We have the know-how, now it is time to join with battery corporations who’re decided to handle the difficulty of kid security and battery use.” 

Along with assist from the college and Viclink, Okay has been working with the Ministry of Enterprise, Innovation and Enterprise (MBIE), Starship Hospital, Safekids NZ, and Energizer to check and develop the coating.

“It is a very thrilling innovation and a terrific instance of Kiwi ingenuity addressing a really actual and severe hazard in a sensible and cost-effective means,” mentioned MBIE’s Martin Rushton.

Okay mentioned his invention was well timed given the recent announcement in New Zealand of a new Product Safety Policy Statement for button batteries, which urges the battery trade to make merchandise safer via improved packaging, show, and disposal, and encourages innovation in battery security.

When a child swallows a button battery it begins to burn the surrounding tissue. It can lead to serious injury or death.
