A sensor in bed monitors an elderly person

06.05.2007

British scientists have created a sensor system that allows you to monitor an elderly person. As the share of old people in the population of developed countries grows, which is caused both by improved medical care, and an increase in the standard of living, and a decrease in the birth rate, the task arises: to provide the elderly with a comfortable independent life and enable young relatives to monitor the health of their separately living loved ones. .

One version of such a system was created by scientists from the University of Southampton, led by professors Bashir al-Hashimi and David de Roor. Its basis is a wireless network of sensors embedded in a variety of home furnishings. These sensors will constantly monitor the surrounding space and record changes in the state of health. For example, a weight sensor built into the bed mattress detects the movements of the person lying on it.

Sensors in the bathroom and toilet will allow you to monitor the use of the bathroom and notice food-related problems in time. Heat sensors built into armchairs and chairs will be able to detect areas with elevated temperatures on the body - places of possible inflammation.

According to the authors of the development, in the next 12 months they will be able to mount a prototype of such a smart room, which is able to monitor the person in it. True, the question remains: can such a life be called independent?

The existence of an entropy rule for quantum entanglement has been proven 09.05.2024

Quantum mechanics continues to amaze us with its mysterious phenomena and unexpected discoveries. Recently, Bartosz Regula from the RIKEN Center for Quantum Computing and Ludovico Lamy from the University of Amsterdam presented a new discovery that concerns quantum entanglement and its relation to entropy. Quantum entanglement plays an important role in modern quantum information science and technology. However, the complexity of its structure makes understanding and managing it challenging. Regulus and Lamy's discovery shows that quantum entanglement follows an entropy rule similar to that for classical systems. This discovery opens new perspectives in the field of quantum information science and technology, deepening our understanding of quantum entanglement and its connection to thermodynamics. The results of the study indicate the possibility of reversibility of entanglement transformations, which could greatly simplify their use in various quantum technologies. Opening a new rule ... >>

New method for creating powerful batteries 08.05.2024

With the development of technology and the expanding use of electronics, the issue of creating efficient and safe energy sources is becoming increasingly urgent. Researchers at the University of Queensland have unveiled a new approach to creating high-power zinc-based batteries that could change the landscape of the energy industry. One of the main problems with traditional water-based rechargeable batteries was their low voltage, which limited their use in modern devices. But thanks to a new method developed by scientists, this drawback has been successfully overcome. As part of their research, scientists turned to a special organic compound - catechol. It turned out to be an important component that can improve battery stability and increase its efficiency. This approach has led to a significant increase in the voltage of zinc-ion batteries, making them more competitive. According to scientists, such batteries have several advantages. They have b ... >>

Alcohol content of warm beer 07.05.2024

Beer, as one of the most common alcoholic drinks, has its own unique taste, which can change depending on the temperature of consumption. A new study by an international team of scientists has found that beer temperature has a significant impact on the perception of alcoholic taste. The study, led by materials scientist Lei Jiang, found that at different temperatures, ethanol and water molecules form different types of clusters, which affects the perception of alcoholic taste. At low temperatures, more pyramid-like clusters form, which reduces the pungency of the "ethanol" taste and makes the drink taste less alcoholic. On the contrary, as the temperature increases, the clusters become more chain-like, resulting in a more pronounced alcoholic taste. This explains why the taste of some alcoholic drinks, such as baijiu, can change depending on temperature. The data obtained opens up new prospects for beverage manufacturers, ... >>

A class of materials with variable mechanical properties has been created 20.05.2012

Scientists at the Karlsruhe Institute of Technology (KIT) have succeeded in creating a new class of materials that can have almost any mechanical properties.

Based on new stable crystalline metafluids, it is possible to create, for example, unique acoustic prisms and completely new acoustic and optical systems.

The new material belongs to the pentamode class proposed in 1995 by Graham Milton and Andrey Cherkaev. Then it was a purely theoretical concept of the mechanical behavior of materials such as gold or water, expressed in compression and shear parameters. For example, water cannot be compressed in a cylinder, but can be stirred with a spoon, so it can be described in terms of compression and shear.

The word penta is of ancient Greek origin and means "five". In the case of water, five shear parameters are zero, and only one parameter (compression) differs from this value. From this point of view, the ideal state of a pentamode metamaterial corresponds to the state of water, which is why these materials are called metafluids. Theoretically, by changing the appropriate parameters, it is possible to obtain a material with any conceivable mechanical properties. But so far it has not been possible to create pentamode material.

German scientists have created a prototype of a unique polymer whose mechanical behavior is determined by the sharpness and length of four individual "beams" of an artificial base nanostructure. This required a number of difficult conditions to be met. On the one hand, it was necessary to create specific structures in the nanometer range and connect them to each other at right angles. On the other hand, it was necessary to create a full-fledged large three-dimensional structure, in other words, a "piece of material".

To do this, I had to use the laser beam recording technique developed by Nanoscribe. It consists in structuring light-sensitive materials in three dimensions using a pulsed laser and allows the production of complex microscopic structures of a given shape.
