Wearable medical devices are an important part ラーメンベット 入金不要ボーナス 出金 future of medicine and a key focus of researchers around the world. They open the door for long-term continuous monitoring of patients outside ラーメンベット 入金不要ボーナス 出金 medical setting to give clinicians an accurate picture of what's happening and a better chance to effectively treat their ailments.
Researchers at The University of Texas at Austin have developed an electroencefalography (EEG) electrode that patients wear on their head to monitor brain activity. The EEG electrodes system could act as a ラーメンベット 入金不要ボーナス 出金 (BCI), which can be controlled by brain signals to help repair damage to the brain caused by strokes and other disorders.
This electrode, shown in a new paper published in the journal Biosensors and Bioelectronics, can be worn comfortably and stable for up to four weeks, without the potential need for any medical personnel to intervene to maintain it. This is a big improvement on what's available today, as these types of electrodes typically need to be replaced every few hours or days at best.
"We're hopeful people can wear this at home for long periods and do their rehabilitation there instead of having to come into the clinic or rehabilitation center every day for weeks, which is even more challenging when you are recovering from a stroke," said Huiliang (Evan) Wang, an assistant professor in the ラーメンベット 禁止ゲーム of ラーメンベット 入金不要ボーナス 出金’s Department of Biomedical ラーメンベット 入金不要ボーナス 出金 and one of the leaders of the project.
EEG electrodes today come in two main types, dry and wet, neither of which work well for consistent long-term monitoring. Wet electrodes, which are gel-based, do a better job of recording ラーメンベット 入金不要ボーナス 出金 activity but require a lot more maintenance than dry electrodes.
The researchers' new electrode has the benefits of a wet, gel-based electrode, and eliminates major drawbacks, such as their tendency to dry out and then fall off. The project builds on a promising solution in early ラーメンベット 入金不要ボーナス 出金 phases that involves using conductive polymers as the basis for the electrodes.
The researchers took this idea to the next level by using conductive polymers together with polymers with high water content. That allows them to take advantage ラーメンベット 入金不要ボーナス 出金 benefits of gel-based materials, primarily that they can give accurate recordings despite interference caused by the skin and hair, a concept known as electrode-skin impedance.
Wang and his team joined up with faculty from the Chandra Family Department of Electrical and Computer ラーメンベット 入金不要ボーナス 出金: professor José del R. Millán and assistant professor Yaoyao Jia, both experts in BCI. Together, they developed and characterized the new EEG electrode-based BCI system.
The electrode system records brain activities, such as the brain telling the hand to move. However, a stroke destroys the neural pathways between parts of the body, making it harder to send the signal for action. The combined ラーメンベット 入金不要ボーナス 出金 and functional electrical stimulation could translate thoughts about moving a body part into actions that stimulate the targeted area to carry out the brain's command. This approach could help to rebuild communication pathways between the brain and the rest of the body that was damaged by a stroke.
“These new EEG electrodes have the potential to revolutionize the field of non-invasive BCI, which currently requires substantial expert support to set up the system every session,” Millán said. “Further, since mastering a BCI – and inducing functional recovery as well as ラーメンベット 入金不要ボーナス 出金 plasticity – requires subject training, having a permanent system that people can utilize all day long autonomously will boost the potential of this technology.”
The next step for the researchers is expanding how long the electrode can be worn and the kinds of activities this wearable EEG-based ラーメンベット 入金不要ボーナス 出金 can facilitate. They're also looking at applications such as controlling a wheelchair, moving prosthetic limbs and more.
