Queen\u2019s University Belfast<\/a><\/p>\n<\/p>\n
Queen’s University Belfast scientists have designed a new flexible organic battery that could revolutionise how medical implants are powered.<\/p>\n
Devices such as pacemakers are currently fitted with rigid metal based batteries, which can cause discomfort.<\/p>\n
The charge in the batteries is set to last three times as long as in their conventional counterparts.<\/p>\n
As it is decomposable, the organic battery is also expected to have environmental benefits.<\/p>\n
Research leader Dr Geetha Srinivasan from Queen’s University’s Ionic Liquid Laboratories (QUILL) research centre said the device was also non-flammable and had no leakage issues.<\/p>\n
She said the “flexible supercapacitor” could be used to power body sensors such as pacemakers.<\/p>\n
“In medical devices such as pacemakers and defibrillators there are two implants, one which is fitted in the heart and another which holds the metal based, rigid batteries – this is implanted under the skin,” said Dr Srinivasan.<\/p>\n
“The implant under the skin is wired to the device and can cause patients discomfort as it is rubs against the skin.<\/p>\n
“For this reason batteries need to be compatible to the human body and ideally we would like them to be flexible so that they can adapt to body shapes.”<\/p>\n
Foldable laptops?<\/h2>\n
Dr Srinivasan said the new battery would be safer than the batteries currently in use.<\/p>\n
“It avoids using flammable solvents, therefore you don’t have the hazard of explosion,” she said.<\/p>\n
The technology could also have a non medical application in foldable phones or laptops of the future, the designs of which are currently constrained by rigid batteries.<\/p>\n
“Everyone wants to go lightweight and everyone wants to be flexible,” Dr Srinivasan said.<\/p>\n
“If the battery goes flexible the whole electronics and equipment can go flexible, it’s interesting and exciting.”<\/p>\n
While current batteries contain toxic materials that are complicated to recycle, organic batteries would simply decompose over time.<\/p>\n
The new device would be manufactured with organic composites using “natural feedstock” (biomaterials such as cellulose) rather than expensive metals or semiconductors.<\/p>\n
But there is no danger of the organic batteries decomposing in the human body as they only start to break down at temperatures above 270C.<\/p>\n
With the right funding in place, Dr Srinivasan said the devices could easily be commercialised – so that it could be powering phones or similar devices within the next five years.<\/p>\n
