According to Cnet, although there are some commercially available products for monitoring human heart rate and maximum oxygen content (VO2 max) on the market today, researchers have made new efforts to better benefit people. We hope to further develop ultra-miniature sensors suitable for real-time tracking of any organs, muscle structures, and even nerve tissues in the human body. Then it promotes the use of artificial limbs, the development of fitness tracking devices, and even the treatment of epilepsy and other illnesses.
If the development of "semi-robots" in the future is cool enough, then we may be able to see that this technique called "neural dust" has been widely used. It simulates the body's nerves and muscles and enters an "electroceutical" to treat epilepsy or inflammation. This means that we are ushering in a new era of the use of bio-electronics to treat diseases.
And just recently, the emergence of a sand-sized ultra-miniature sensor made these ideas a reality. This special sensor was developed by engineers from the University of California, Berkeley. Ultrasound can also be used to power implanted devices and transmit data. Currently, researchers have successfully implanted nerve dust in the muscles and nerves of rats and hope to create smaller sensors that can be used to implant the brain.
(a nerve dust)
"In the long run, the prospect of nerve dust is not limited to nerves and brains. It will be applied to a wider range of fields. In vivo bio-telemetry has not been possible in the past, because we could not find implants with particularly small devices in the depths of the body. But now we can implant sand-sized devices into nerves, organs, gastrointestinal tracts, or muscles and read the data.â€
At present, when using artificial limbs, most of the electrodes used by the disabled to control the prostheses need to be connected to electrode wires that pass through the holes in the skull. This electrode wire has a life span of only a few years and is prone to infection. The use of smaller-sized nerve dust allows the wireless sensor to be permanently positioned and sealed in the skull, reducing the risk of infection and unnecessary inconvenience caused by the electrode wire.
A paper on this new technology written by Michel Maharbiz, a professor of engineering and computer science at the University of California, Berkeley, and other researchers published in Neuron magazine. He said that the research team is working hard to develop micro sensors that are compatible with the human body, and that these sensors will last for at least 10 years and will not degrade performance.
"The beauty is that this type of sensor is small enough to be well used in the peripheral nervous system. For example, you can use it to suppress appetite," wrote University of Berkeley professor, neurologist and co-author of the above thesis. Jose Carmena pointed out, “But this technology has not yet reached a stage where we can implant targets within 50 micron. If we reach this stage, we can implant sensors in the brain and central nervous system. Once it has been clinically proven, nerves Dust will replace the electrode wire. If we can overcome the problem of implanting the brain, our research will be completed."
However, in order to realize this idea, scientists still have much work to do. Human trials have not yet started. It is still a long way to go before the nerve dust is actually used in the medical field.
