Replication of the human olfactory system and the human perception of taste by electronic means have been attempted by scientists. The prototypes are referred as electronic nose and electronic tongue and comprises of compound specific sensors active in gaseous and aqueous medium respectively. Though the electronic prototypes have found conceptual acceptance, the commercialization of the same has been a distant reality. In the present form the areas of utility for the models includes detection and discrimination of complex compounds. The discrimination is based on the variation in the amount...

The aim of this study is to design and develop a low-power wireless patient monitoring system that should be easy to integrate with other technologies or infrastructures at a low cost, This transmitting unit should be able to replace many of the signal wires between biomedical sensors used for monitoring the patient and the sampling unit or supervision equipment. The model of hardware solution is combination of microcontroller (Atmega 32) , Xbee & distance sensor. The communication between PC to PC or between PC to Xbee controlled by the Atmega 32 microcontroller .The results indicate that...
