Monitoring of sweat secretion from eccrine sweat glands using electric conductivity method

Foltyński P., Ładyżyński P., Wójcicki J. M.

Vol. 32, no. 4

Sweat secretion from a single sweat gland can be monitored by using microtube or by visual observation of the skin region using a microscope or video recorder. Another method described in the present paper is based on perfusion with ultra-low conductive water of a small region of the skin with only one sweat pore. Sweat secreted from a gland is reach in ions comparing to perfusion fluid and therefore increases conductivity of the perfusion fluid. Conductivity of the perfusion fluid is measured on inlet and outlet of the measurement probe and the difference is amplified and sampled by an analog-to-digital converter controlled by developed software on PC. The goal of the present paper is to present an improved system of single sweat glands monitoring.

A method providing monitoring of activity of a single sweat gland by measurement of electric conductivity of perfusion solution has been developed recently. The aim of this project was to design and develop a mesurement system employing the electric conductivity method, which could simultaneously monitor the sweat secretion from four sweat glands. The measurement chamber was developed to use in the measurement system. In vivo measurements using developed system were carried out. Detailed measurement procedure has been presented. The results proved proper operation of the designed system.
