Stress is an escalated psycho-physiological state of the human body emerging in response to a challenging event or a demanding condition. Environmental factors that trigger stress are called stressors. In case of prolonged exposure to multiple stressors impacting simultaneously, a person’s mental and physical health can be adversely affected which can further lead to chronic health issues. The negative effects of mental stress on human health has been known for decades. High-level stress must be detected at early stages to prevent these negative effects. The stress response allows the body to overcome obstacles and prepare for threats, but sustained levels of stress can damage one’s health. The aim of this paper is to design an IoT base wearable, cost effective and low power smart band for health care that detect mental stress based on skin conductance. This band can monitor user's mental stress continuously and transmit the stress related data wirelessly to user's smart phone. It not only help the users in better understanding their stress levels but also provide the physician with reliable data for a much better treatment. Inputs to this device are various signals from different sensors.Stress is an escalated psycho-physiological state of the human body emerging in response to a challenging event or a demanding condition.
