Smart t-shirt

23.09.2004

A British student came up with a T-shirt that monitors the health of an athlete.

I thought for a long time that it would be a good idea to monitor the health of an athlete directly during the game, however, when in 2003 Cameroon midfielder Mark Vivien Fomer was on the field from a heart attack, I decided to take it seriously, "says David Evans from the University of Northumbria.

The result is a "smart" T-shirt. An ECG sensor is fixed on it, which captures the electrical activity of the heart and sends the data through a micro-radio transmitter sewn to the hem of the T-shirt to the trainer's computer. Sweat sensors based on silica gel tourniquets are stretched along the back of the athlete. And another sensor is hidden in the sleeve - it receives a radio signal from the coach and informs the player with a slight vibration: look at the team bench, they want to tell you something.

Having information about the work of the heart, especially about its violations, the coach and doctors can understand in time that the player is tired and it is time to replace him. A decrease in sweating indicates dehydration - in order to restore strength, a football player needs to urgently drink water.

"The T-shirt I made has already caught the interest of sportswear manufacturers and I hope it will be updated for the 2006 World Cup," says David Evans.

Improving the efficiency of PbS quantum dot solar cells 14.06.2024

The latest solar technology research represents a significant breakthrough in improving the efficiency of PbS quantum dot solar cells. This method, based on the use of pulsed light, offers promise for simplifying the production and expanding the applications of these cells. A research team from the Daegu Gyeongbuk Institute of Science and Technology has developed an innovative method that uses pulsed light to improve the electrical conductivity of PbS solar cells. This method can significantly reduce the processing time required to achieve similar results. PbS quantum dot solar cells have significant potential in solar technology due to their photovoltaic properties. However, the formation of defects on their surface can reduce their performance. The new method helps suppress defect formation and improve electrical conductivity. Using strong light to complete the process ... >>

Magnetic Power Bank 5000mAh 14.06.2024

Huawei introduces a convenient and multifunctional charger to the market - Huawei SuperCharge All-in-One Magnetic Power Bank. This magnetic battery allows you to quickly and conveniently charge your Huawei phone anywhere, anytime.

The power bank is also compatible with Huawei phones that support wireless charging. ... >>

Changes in a father's brain after the birth of a child 13.06.2024

A recent study conducted by scientists from the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences found interesting changes in the brains of men after becoming fathers. These changes were associated with involvement in child care, sleep problems, and mental health symptoms. Scientists found that men who became fathers experienced a loss of brain volume after giving birth. This volume loss was associated with greater involvement in parenting, sleep problems, and mental health symptoms. Researchers have found significant changes in men's brains between the prenatal and postnatal periods. In particular, there was a loss of gray matter volume, especially in parts of the brain responsible for higher functions such as language, memory, problem solving and decision making. Men who paid more attention to their children and spent more time with them lost more gray matter in their brains. This also affected their mental health ... >>

Smartwatch that analyzes the composition of sweat 13.06.2024

Scientists from the Hefei Institute of Physical Sciences of the Chinese Academy of Sciences presented an innovative smartwatch that can analyze the composition of sweat. This device can be a valuable tool for athletes, allowing them to monitor changes in the body during training and competition. The device is equipped with various sensors that can process sweat from the human body and analyze the chemicals in its composition. Using sensors, you can accurately determine the levels of potassium, sodium and calcium ions. Sweat composition indicators can be monitored both in real time and over a period of six months. This allows athletes to receive continuous feedback on the state of their body during training and recovery. Smartwatch sensors are based on electrochemical methods and use a microfluidic chip that can process very small volumes of liquid. This makes it possible to study the composition of even 0,01 ml of sweat. Stability of sensors is a key aspect ... >>

Wine is safer than beer 12.06.2024

A University of Adelaide study has found that drinking alcohol in moderation may be less harmful to heart health than previously thought. Researchers have studied the effects of different types of alcohol on the risk of developing atrial fibrillation (AF), one of the most common forms of arrhythmia that can lead to serious heart complications. Atrial fibrillation is an irregular and rapid heartbeat that increases the risk of stroke, heart failure and other serious heart problems. Symptoms may include rapid heartbeat, shortness of breath, and weakness. Excessive alcohol consumption is known to increase the risk of developing AF, but the effect of small doses of alcohol remains unclear. The study was based on data from the UK Biobank, a large-scale database containing health information on half a million British volunteers. The study's lead author, Samuel Tu from the University of Adelaide's Center for Heart Rhythm Disorders, reports ... >>

Drones and Coronavirus 12.06.2021

Malaysian police use drones that can measure temperatures up to 20 meters above the ground. This is another measure to combat the spread of coronavirus. Drones alert regulators to people with high temperatures.

Malaysian police have previously warned they will use drones to enforce previously imposed travel restrictions, and officers in some areas have also said they will be making surprise home visits to make sure people are following the rules.

Previously, reports have already appeared about how the authorities of various countries used unmanned aerial vehicles to monitor compliance with COVID-19 rules. The Spanish authorities have used drones to make sure people visiting beaches are following social distancing rules. In Brussels, Belgium, police used drones with loudspeakers to urge people to "stay at home".

In Australia, drones have been used to catch people without masks, as well as to scan cars parked more than 5km from their owners' homes. In the UK, authorities have come under fire for using drones to monitor dog owners to see if they stray too far from home.
