Smart sensors techniques for monitor comatose patient using embedded system

Abstract

Unconsciousness is a state of unawareness of self and environment of those mental activities by which people are made aware of themselves and their environment, coupled with a diminished responsiveness to environmental stimuli. Smart sensors are mostly used in aeronautical, computer and for gesture recognition in biomedical application. This system designed and developed a reliable, energy efficient for sending alert message to the concern person when person in coma. The system used smart sensors like flex sensor, MEMS body sensor and eye blink sensor. Whenever person moves any finger, any eye lid and tilt the body towards right or left side, the flex sensor, eye blink sensor and MEMS sensor detects the movement respectively, and alert to the concern person through GSM.
