The Development of Portable System for Unobtrusive Perspiration Monitoring

Portable system for monitoring of excreted fluid through the skin during human activity has been developed and fabricated. The system consists of sensing element that is mounted close to the open skin surface and transmits information about relative humidity levels and temperature through wireless communication to coordinator unit and acquisition point which is equipped by analyzing software performing the calculation of excreted fluid through the skin surface. A special software utility is designed for data storage and user control of the main measured and stored parameters. Obtained information collected in time helps to determine the volume of fluid outgoing from the body by sweating. Basic communication with PC is realized by COM port, virtual port or Bluetooth COM port emulator. The volunteers’ tests demonstrated perspective for using the system for athletes, active lifestyle people and elderly people.
