Abstract :
The monitoring of acute and later stages of changes of intracranial pressure (ICP) is of great importance in studies of the effects of hydrocephalus and traumatic brain injury. It also aids in determining the outcome of treatment. A digital prototype for wireless ICP measurement based on Texas Instrument´s CC2500 2.4 GHz transceiver and MSP430 ultra-low-power microcontroller has been designed, investigated, and tested. In-vitro evaluations under different circumstances are described to demonstrate the repeatability, stability, and reliability of the device.
