【 摘 要 】

Electro-dermal Response (EDR) is one of the important bioelectric signals used in various applications and research studies in the multitude of disciplines, such as Psychophysiology and other areas of Neuroscience. In present paper, a low cost EDR system is designed using Texas Instrument's MSP430 Value Line Launchpad with a general potential divider circuit as the EDR sensor. Throughout this paper, much emphasis is laid out on developing an inexpensive system that shall be easily affordable while offering quality measurements. The system is well incorporated to have a decently accurate and fast data acquisition system, good communication capability with PC for storage and analysis. The developed prototype was used in performing two experiments related to the effects of Deep Breath and Visual Stimulus on EDR data, which gave substantiating results as per the theory.
