Methods based on salivary amylase activity to quantify the psychological stress have reported successes. There was a need for a non-invasive method to assist the individual in monitoring stress since stress is now the leading cause of diseases. The purpose of this research was to develop of microcontroller based potentiometric indicator system for a salivary biosensor using surface mount component.

For software subsystem, the stress level indicator system has been developed using PIC 16F873 by converting the output from potentiometric circuit into stress level with a look-up table based on fuzzy rule sets for measuring human stress. It computes the digital data conversion into desired reading and displays data through the second hardware subsystem which is liquid crstal display. A potentiometric indicator for a piezoresistive MEMS biosensor to detect human stress was developed. It was comprised of a potentiometric transduction stage, filtering stage and linearization stage.
