15 wrz 2021 · The roughness, water contact angle, sweat pore size, and sweat pore density of human skin were reproduced using embossing with sweat pores (approximately 80 μm diameter) laser micromachined to enable the model to ‘sweat’.
Regulate body temperature through pores at skin surface; produces clear sweat (Eccrine= palms, soles of feet, forehead. Apocrine= armpit, genital- release sweat that contains fatty acids and proteins in puberty)
The perspiration simulation works found in the literature model the sweat gland as a fluid conduit, discarding to replicate their role on sweat generation. Sweat generation, which takes place in the secretory coil, is replaced by pumping mechanisms, such as syringe pumps and hydrostatic pressure.
4 maj 2021 · In addition to epidermal and dermal components, the inclusion of appendages such as sweat glands (SGs) and hair follicles (HFs) is important for modeling the physiological functions of 3D skin tissue constructs .

We use here coherent Raman scattering imaging (CARS and SRS) to follow active compounds as they penetrate into reconstructed skin models and human skin samples together with endogenous two-photons excited fluorescence (TPEF) and second harmonic generation (SHG) that provide morphological contrast.
21 lut 2021 · The predominant approach to replicate the key features of perspiration (sweat gland dimensions, sweat rates, and skin surface characteristics) is to use laser-machined membranes. Although they work effectively, they present some limitations at the time of replicating sweat gland dimensions.
