A Custom Computer-Controlled Fluid Mixing and Dispensing System for Sweat Sensor Testing Applications
We propose a completely automatized, computer-controlled fluid mixing and dispensing system that is suitable for testing sweat sensing devices. The design is based on Raspberry Pi that controls almost a dozen electronic relays and switches. Easy to use graphical user interface allows end users conduct the tests without any technical problems. A dragon skin based arm mold was also prototyped with pores to simulate a close to real-life arm prototype that sweats. Relay controlled mixing tanks allow different concentration of fluid solutions at various rates of fluid dispensing through pores. With the recent advances in sweat sensors, this platform offers a unique way of testing developed sensing devices before human tests both in development and before testing phases.
