The aim of the experiment was to bring closer the possibilities of using corona discharge photography (CDP), with special emphasis on the impact of textiles on corona discharge photography of human fingertips in contact with those textiles. The article describes an investigation concerning a short period of contact with textiles and their influence on human parameters such as blood pressure (BP) and heart beat (HB) as well as images of corona discharges (ICD). The authors were searching for a new method of demonstrating the influence of textiles on human subjects. As the research involved contact of textiles with human skin, certain static and friction issues were raised. Textile materials were chosen for the experiments on the basis of their tribological features. The ICDs used here were created as a result of placing body parts, e.g. fingers, in the area of a strong electrical field of high voltage (10 KV) and high frequency (1024 Hz). A digital camera placed within the area of discharge recorded this phenomenon. The temperature, air humidity, and air pressure in the examination room as well as gender, age, HR, BP and in the case of female volunteers, their menstrual cycles, exerted an effect on ICD in the study group. ICD of human beings seems to be a kind of marker of tribological features of textile materials.
