Fabric that feels warm and cold

06.11.2023

A team of MIT scientists has unveiled a programmable fiber called FibeRobo that can sense temperature and change its shape. Requiring no built-in sensors or rigid components, this fiber contracts as the temperature rises and returns to its original state as the temperature drops.

Experts say this affordable fiber integrates easily with textile manufacturing technologies. It allows designers to integrate activation and sensors into different types of fabrics for different purposes. Additionally, the fibers can operate with an electric current passing through the filament as a heating element, allowing users to digitally control the shape of the textile.

Currently, existing shape-changing fibers have limitations that prevent their use in the textile industry. MIT researchers have developed FibeRobo, which can silently activate and change its shape. The fiber can shrink by 40%, activate at skin-safe temperatures and cost as little as 20 cents per meter.

Scientists have used FibeRobo to create an adaptive sports bra that tightens when the wearer is physically active. In the future, they plan to tweak the chemical components of the fiber to make it recyclable or biodegradable.

Note that the research startup Milbotix introduced socks with artificial intelligence - SmartSocks. Free of wires and batteries, these socks are equipped with sensors that collect the wearer's physiological information and send it to a mobile app via a cloud platform. The machine learning system analyzes the data and, if an anomaly is detected, alerts the palliative staff, which allows them to take the necessary measures in a timely manner to save life.

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, ... >>

Major risk factor for gambling addiction 07.05.2024

Computer games are becoming an increasingly popular form of entertainment among teenagers, but the associated risk of gaming addiction remains a significant problem. American scientists conducted a study to determine the main factors contributing to this addiction and offer recommendations for its prevention. Over the course of six years, 385 teenagers were followed to find out what factors may predispose them to gambling addiction. The results showed that 90% of study participants were not at risk of addiction, while 10% became gambling addicts. It turned out that the key factor in the onset of gambling addiction is a low level of prosocial behavior. Teenagers with a low level of prosocial behavior do not show interest in the help and support of others, which can lead to a loss of contact with the real world and a deepening dependence on virtual reality offered by computer games. Based on these results, scientists ... >>

Traffic noise delays the growth of chicks 06.05.2024

The sounds that surround us in modern cities are becoming increasingly piercing. However, few people think about how this noise affects the animal world, especially such delicate creatures as chicks that have not yet hatched from their eggs. Recent research is shedding light on this issue, indicating serious consequences for their development and survival. Scientists have found that exposure of zebra diamondback chicks to traffic noise can cause serious disruption to their development. Experiments have shown that noise pollution can significantly delay their hatching, and those chicks that do emerge face a number of health-promoting problems. The researchers also found that the negative effects of noise pollution extend into the adult birds. Reduced chances of reproduction and decreased fertility indicate the long-term effects that traffic noise has on wildlife. The study results highlight the need ... >>

A New Way to Control and Manipulate Optical Signals 05.05.2024

The modern world of science and technology is developing rapidly, and every day new methods and technologies appear that open up new prospects for us in various fields. One such innovation is the development by German scientists of a new way to control optical signals, which could lead to significant progress in the field of photonics. Recent research has allowed German scientists to create a tunable waveplate inside a fused silica waveguide. This method, based on the use of a liquid crystal layer, allows one to effectively change the polarization of light passing through a waveguide. This technological breakthrough opens up new prospects for the development of compact and efficient photonic devices capable of processing large volumes of data. The electro-optical control of polarization provided by the new method could provide the basis for a new class of integrated photonic devices. This opens up great opportunities for ... >>
