Abstract
A system and method for measuring and communicating parameters of a brain, tissue, or other organs is disclosed. The system includes a sensor to sense the parameter of interest, an external device where the parameter may be displayed, processed or cause action to be taken, and a communication system to communicate the sensed parameter from the sensor to the external device. In another embodiment, the system includes a processing system for processing the sensed parameters and controlling an associated medical device.
