Abstract

In this paper we present for the first time a wireless self-calibrating pressure sensor for biomedical applications and especially for IntraCranial Pressure (ICP) monitoring. The proposed system consists of a piezoresistive pressure sensor implemented at the end of a catheter tube and connected to a wireless transceiver placed on the patient's head. The auto calibration capability of the proposed sensor enables to avoid the existing problem of drift with time and hence provides an excellent solution for long term monitoring.
