Development of Galvanic Skin Response Sensor System to Measure Mental Stress

Stress is a very normal reaction when a person is feel threaten or upset in some way. Generally, stress happen when a person ability is not able to meet with the situational demands. It can be either positive or negative. Stress can give a person to have high concentration to face certain circumstances as well as better reaction to handle difficult situation. On the other side, it can also cause sickness to a person if one is suffer from overstress. A person will have health issues like the risk of depression and neurological disorders like stroke if mental stress level is too high. Thus, a device is necessary to measure the stress level so that the stress level can be regulate before it is out of control. Although there are several of methods in the market that are able to measure the stress level, but there are all expensive and complicated. Thus, this project will be focusing on developing a Galvanic Skin Response Sensor that are able to measure stress level based on the skin conductivity. GSR sensor is an economical tool to measure stress level with simpler analysis. Complete methodology and findings are shown as we go through the report.
