The US Army is seeking to develop a new device that can optimize the flow of brain and spinal fluid so that soldiers deployed in difficult tasks can improve sleep.

Researchers from many universities in the United States are used to measure and regulate the flow of cerebrospinal fluid, which helps the brain by expelling waste products during sleep. It also helps to absorb shocks and cushion sudden movements.

The goal of a project is to create a lightweight hat that can be used in any situation and is easy to transport. Paul Cherukuri, Director of the Institute of Biological Sciences and Bioengineering at Rice University (RU), explained: “The Ministry of Defense asked us if we could design a small portable hat that could measure and regulate combat during sleep. People’s brain health to improve their performance."

RU engineers and doctors from Houston Methodist Hospital and Baylor College of Medicine will lead the first year of development of the technology project.

The military recognizes that soldier fatigue is a key issue that needs to be resolved in order to achieve better performance in military operations.

For this service, observing and analyzing the human lymphatic system may be a solution to help soldiers get a good rest. In addition to removing waste, the cerebrospinal fluid of the system can also remove dysfunctional proteins in the soldier's brain, thereby enhancing the "brain recovery ability."

During the observation phase of the project, the researchers plan to try a variety of techniques, including ultrasound brain stimulation or electromagnetic signals. All data and information collected from the ongoing research will be analyzed using the machine learning software being developed by RU.

The preliminary results of the research and development of the experimental "Nightcap" project are expected to be released within one year.
