E-textile touch button placement with a help–request function for smart sportswear

Abstract

Due to the high risk of injury to an athlete during sports training, the diagnostic and monitoring functions of sportswear are among the most potentially demanded. The article is devoted to the investigation of optimal topographic areas for a textile touch button placement with a help–request function. A touch button is part of a flexible printed circuit board that is integrated into the structure of highly functional, tight-fitting sportswear. It was determined that the button should be placed so that an athlete takes the minimum amount of time to move and press the button. In this paper, the minimum values of the modulus of a vector of the athlete's hand movement when pressing a touch button after a sudden deterioration of the athlete's health were determined. The study was carried out by measuring the trajectory lengths in dynamic postures that constitute the phase schemes of falls on the example of athletes performing plyometric jumping, walking, and running, as well as in static positions.
