The electronic patch will inform about the health of the patient

25.08.2017

Until recently, medical system sensors placed on a patient's body to collect health data were bulky and uncomfortable to wear. The use of new technologies has allowed scientists to create sensors the size of a coin and as thick as adhesive tape.

The smart patch, created by Kyung-In Jang, Professor of Robotics at the Korea Institute of Science and Technology (DGIST) and John A. Rogers from Northwestern University (USA), consists of a silicone body containing " 50 components connected by a network of 250 tiny wire spools." The silicone adheres tightly to the body and the sensor transmits data on "movement and breathing, as well as the electrical activity of the heart, muscles, eyes and brain."

Unlike flat gauges, tiny wire coils can stretch and compress like a spring without breaking their integrity. Coils and sensor components are configured in a web-like system that provides "uniform and extreme levels of stretch and flexibility in any direction". This also provides a more compact arrangement of components, minimizing the size of the device.

The sensor can be connected to a wireless network, which means that it can be placed almost anywhere on the body. In the future, it is planned to use this system in robots when a more flexible connector is required.

Dong said he intends to continue further research into the development of electronic patches that will provide access to interactive treatment systems and telemedicine services for patients in areas that are difficult to access medical services, such as villages in the mountains.

Air trap for insects 01.05.2024

Agriculture is one of the key sectors of the economy, and pest control is an integral part of this process. A team of scientists from the Indian Council of Agricultural Research-Central Potato Research Institute (ICAR-CPRI), Shimla, has come up with an innovative solution to this problem - a wind-powered insect air trap. This device addresses the shortcomings of traditional pest control methods by providing real-time insect population data. The trap is powered entirely by wind energy, making it an environmentally friendly solution that requires no power. Its unique design allows monitoring of both harmful and beneficial insects, providing a complete overview of the population in any agricultural area. “By assessing target pests at the right time, we can take necessary measures to control both pests and diseases,” says Kapil ... >>

The threat of space debris to the Earth's magnetic field 01.05.2024

More and more often we hear about an increase in the amount of space debris surrounding our planet. However, it is not only active satellites and spacecraft that contribute to this problem, but also debris from old missions. The growing number of satellites launched by companies like SpaceX creates not only opportunities for the development of the Internet, but also serious threats to space security. Experts are now turning their attention to the potential implications for the Earth's magnetic field. Dr. Jonathan McDowell of the Harvard-Smithsonian Center for Astrophysics emphasizes that companies are rapidly deploying satellite constellations, and the number of satellites could grow to 100 in the next decade. The rapid development of these cosmic armadas of satellites can lead to contamination of the Earth's plasma environment with dangerous debris and a threat to the stability of the magnetosphere. Metal debris from used rockets can disrupt the ionosphere and magnetosphere. Both of these systems play a key role in protecting the atmosphere and maintaining ... >>

Solidification of bulk substances 30.04.2024

There are quite a few mysteries in the world of science, and one of them is the strange behavior of bulk materials. They may behave like a solid but suddenly turn into a flowing liquid. This phenomenon has attracted the attention of many researchers, and we may finally be getting closer to solving this mystery. Imagine sand in an hourglass. It usually flows freely, but in some cases its particles begin to get stuck, turning from a liquid to a solid. This transition has important implications for many areas, from drug production to construction. Researchers from the USA have attempted to describe this phenomenon and come closer to understanding it. In the study, the scientists conducted simulations in the laboratory using data from bags of polystyrene beads. They found that the vibrations within these sets had specific frequencies, meaning that only certain types of vibrations could travel through the material. Received ... >>

Implanted brain stimulator 30.04.2024

In recent years, scientific research in the field of neurotechnology has made enormous progress, opening new horizons for the treatment of various psychiatric and neurological disorders. One of the significant achievements was the creation of the smallest implanted brain stimulator, presented by a laboratory at Rice University. Called Digitally Programmable Over-brain Therapeutic (DOT), this innovative device promises to revolutionize treatments by providing more autonomy and accessibility to patients. The implant, developed in collaboration with Motif Neurotech and clinicians, introduces an innovative approach to brain stimulation. It is powered through an external transmitter using magnetoelectric power transfer, eliminating the need for wires and large batteries typical of existing technologies. This makes the procedure less invasive and provides more opportunities to improve patients' quality of life. In addition to its use in treatment, resist ... >>

The perception of time depends on what one is looking at 29.04.2024

Research in the field of the psychology of time continues to surprise us with its results. Recent discoveries by scientists from George Mason University (USA) turned out to be quite remarkable: they discovered that what we look at can greatly influence our sense of time. During the experiment, 52 participants took a series of tests, estimating the duration of viewing various images. The results were surprising: the size and detail of the images had a significant impact on the perception of time. Larger, less cluttered scenes created the illusion of time slowing down, while smaller, busier images gave the feeling of time speeding up. Researchers suggest that visual clutter or detail overload can make it difficult to perceive the world around us, which in turn can lead to faster perception of time. Thus, it was shown that our perception of time is closely related to what we look at. Larger and smaller ... >>

FingerReader - text reader 11.07.2014

The FingerReader device, similar to a ring, allows you to read and translate any printed matter. A mini-camera is installed on the ring that scans the text, so to read it, just point your index finger with the ring at the desired text.

The software reads the information and recognizes the words. The device is also equipped with a mini-vibration motor, which is launched if the finger is directed to an empty field without text. The voice reproduces words and quickly translate books or, for example, restaurant menus.

The developers believe that the device will be especially popular with blind people, but the convenience of using such a gadget for sighted people is also undeniable - especially as a translator while traveling.

"When I go to my doctor, I often need to sign some documents, but I have to read them first. For this, it is very convenient for me to use this ring. Any device available to us that allows us to have greater access to printed products helps us to live a fuller, richer, richer life," said Jerry Barrier, blind from birth.
