Smart clothes that track posture and movement

21.07.2022

Clothing made of "smart" textiles, developed by researchers from the Massachusetts Institute of Technology, is able to reproduce the postures and movements of a person.

To create models, scientists used a digital knitting machine. They wove a fabric from several rows of conventional and multifunctional piezoresistive yarns, which changes the resistance when compressed.

The multilayer material, called 3DKnITS, was equipped with numerous motion sensors. Thanks to thermoforming technology, their accuracy has been significantly improved.

Scientists noted that when moving, the layers of tissue are shifted and this distorts the performance of the sensors. To solve this problem, the researchers added thermoplastic threads to the material that begin to melt at temperatures above 70 degrees Celsius. Experiments have shown that such threads effectively fuse multilayer knitwear into one layer.

The new technology makes it possible to produce products with complex shapes. Socks, for example, exactly match the wearer's foot size. Sensor data is transmitted via a heat map to a machine learning system that learns to recognize a person’s movement or posture in real time.

The creators of the development emphasized that it could be used in the medical field. So, "smart" socks could track the movements of a person after injuries or strokes, suffering from gait disorders, control pressure on the foot in patients with diabetes.

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, ... >>
