At Tomsk State University of Control Systems and Radioelectronics, a unique electrically heated vest has been developed that can operate autonomously for up to four hours. It can be used for ice diving.
The vest is worn under a dry suit — a suit that isolates the body from water. It is worn as a vest, not like a bulletproof vest over the head. It operates from its own underwater canister light at depths of hundreds of meters.
The vest is completely safe and will work even if water gets inside. The technology used in it helps to retain heat and warms the diver during immersion. This allows for longer underwater work without hypothermia.
The power of this model is 50 W, making it suitable even for use under ice water. At the same time, the vest will retain heat on the surface: it operates from an external power source.
The design provides for heat distribution. The chest area receives 30 watts, while the back receives 20 watts. This is due to the fact that the diver's back cools down less than the chest.
The heated vest, created entirely from domestic materials, is planned to be launched into mass production in 2025.
Earlier, scientists at TUSUR developed and tested a prototype technological installation designed for applying thermal barrier ceramic coatings to gas turbine engine blades. One of the advantages of the domestic development is its compactness, in contrast to larger foreign counterparts. This reduces power consumption and lowers production costs.
