generic real-time wireless communication system
ABSTRACT
Inspite of the improvement of communication link and despite all progress in advanced communication technologies, there are still very few functioning commercial wireless monitoring systems, which are most off-line, and there are still a number of issues to deal with.
In our project, a generic real-time wireless communication system was designed and developed for short and long term remote patient-monitoring applying wireless protocol. The primary function of this system is to monitor the temperature and Heart Beat of the Patient and the Data collected by the sensors are sent to the Microcontroller. The Microcontroller transmits the data over the air by using GSM. At the receiving end a receiver is used to receive the data and it is decoded and fed to Microcontroller, which is then displayed over the LCD display.
Human skin offers some resistance to current and voltage. This resistance changes with the emotional state of the body. The circuit proposed here measures changes in our skin resistance following changes in our mental state. In the relaxed state, the resistance offered by the skin is as high as 2mega ohms or more, which reduces to 500kiloohms or less when the emotional stress is too high. The reduction in skin resistance is related to increased blood flow and permeability followed by the physiological changes during high stress. This increases the electrical conductivity of the skin.
This circuit is useful to monitor the skins response to related to increased blood flow and permeability followed by the physiological changes during high stress. This increases the electrical conductivity of the skin.
