## 1 Introduction
As indicated by the literature data, in addition to the tested microbial strains, chamomile essential oil is active against other bacteria associated with lower urinary tract infections, such as _Staphylococcus aureus_ bacteria, causing mainly hospital infections, and _Proteus_ bacteria, which are responsible for recurrent infections [1; 6; 7]. In addition to pharmacological treatment, a common way to combat lower urinary tract inflammation are steam baths. Some doctors recommend using them from several \begin{table}

Various essential oils are often added to the water, including chamomile, which supports healing and relieves discomfort [12]. However, the use of steam baths is not very comfortable and does not allow mobility during its use. That is why the idea of a biotextronics system (acronym BioTexPants) for preventive and supportive treatment came to be. The system is a kind of a therapeutic clothing in the form of underwater integrated with a four-layer pantiliner with biological active compounds (Figures 1 and 2) [1]. Such a solution is a combination of cosmetotextiles with healing effects. Cosmetotextiles are textiles with active compounds as cosmetic ingredients, which are transferred and have the ability to ensure an optimal exchange in order to generate beneficial effects regarding skin appearance. Through the use of cosmetotextiles, well-being and health can be improved where certain substances or even vitamins could increase skin health. Moreover, these textile materials establish the basis for the delivery system of biologically active substances in contact with the skin [13]. The biotextronics system for the prevention and supportive treatment of lower urinary tract infections consists of underwater (Figure 1(1)) with a permanently attached textronics insert (Figure 1(4)) on which a disposable, replaceable insert with applied essential oil is placed (Figure 1(6)). The outer insert has anti-inflammatory and antibacterial properties thanks to the applied essential oil, released from the insert under the influence of higher temperatures (40 \({}^{\circ}\)C, which is the temperature for therapy). The textronics (heating) insert consists of three layers B-D (Figure 2). Layers B and D are electrically insulating layers, with layer B characterized by good thermal conductivity properties. Layer C is made of electroconductive textile materials, and it is the heating element of the system, connected via a textile signal line (Figure 1(2)) to the regulation system (Figure 1(3)) that ensures
