Numerous solutions for pulse measurement by athletes exist, most commonly in the form of watches or bands. However, some athletes do not tolerate or do not want additional devices on their bodies during exercise. This work aims to replace the existing commercial solutions with textile sensors embedded in clothing. Such a solution would increase comfort and facilitate physical activity. To select the best solution, four knitted fabrics were tested to select the one with the best parameters as a substrate for the system. Three different densities of the embroidery with electrically conductive thread 100%, 85% and 65% were also tested and in two sizes for bands and belts. Mechanical and utility tests were performed such as resistance to perspiration or tensile stress. All tests were carried out in an accredited laboratory, in accordance with applicable standards and our own methodology. The results showed the best material, embroidery density and embroidery size to create an airy, heat-dissipating, and durable textronic system for athletes. Prototype of the solution was created, and its operation was tested during simulation. Conducted tests of the conductive properties of embroidered materials confirm the possibility of making textronic sensors responding to the pulse. The knitted fabrics selected for the tests meet the requirements of sports materials for the parameters of thermal resistance and air permeability. The results showed the correct operation of the prototype. [ABSTRACT FROM AUTHOR] |
