Abstract :
The feasibility of acquiring intracranial pressure information through the scalp at 2.4 GHz ISM band is demonstrated. A device, including a piezoresistive sensor, an oscillator and a chip antenna, irradiates a pressure dependent microwave signal. With the device covered by a scalp phantom, the detected signal is only about 8-13 dB below the case without the phantom.
