Australian researchers are developing a tiny device that treats chronic pain by blocking the pain signals sent to the brain. The technology is being developed by Sydney-based National ICT Australia, and the researchers are planning to conduct human trials of the device in the next year. The INS2 device, which consists of smart chips and a power source, can be placed in the spine or other locations inside the body, where it can be fine tuned to help block chronic pain. The chips emit an electric pulse of up to 10 volts into the target nerve, disrupting the pain signals. The device will also be capable of measuring signals carried by the nerves, allowing it to be fine tuned to manage various levels of pain. The device can be used to treat chronic back, lower limb or nerve damage pain, and can also be used to manage migraines and improve control of Parkinson’s Disease tremors or epileptic seizures.
