Australian scientists on Monday said they are working on a tiny device that promises to have a big impact on treating chronic pain.
The Implantable Neuro Sensing and Stimulatio (INS2) device comprises a smart chip embedded in a biocompatible device smaller than a match head, and it is seen as a major advance on the conventional technology.
The technology, targeting chronic pain, was developed in Australia's Sydney by National ICT Australia (NICTA) over the last two years by experts in biomedical, electrical and mechanical engineering, as well as textile technology and software applications.
"The new NICTA device will be much smaller (than alternatives) allowing it to be located close to the spine, making implant surgery easier and improving device reliability due to the need for shorter connection leads," chief technology officer at the NICTA, Dr John Parker, told ABC News on Monday.
"The device will also be able to measure signals carried by the nerves, allowing it to be fine-tuned to manage different levels of pain."
Dr Parker said the technology could be used to treat not only chronic back, lower limb or nerve damage pain but also help to tackle migraine headaches or improve control of Parkinson's Disease tremors or epileptic seizures.
It also has a tiny computer processor powered by a miniature battery and, unlike conventional devices, the battery is charged wirelessly, ruling out the need for a wire to exit the body.
NICTA is preparing to run medical trials on the miniature implant device in human patients next year.
