FIELD: medicine.SUBSTANCE: devices and methods are provided that are generally related to vibration sensors for fluid external pressure measurement, namely to sensors configured to be implanted. The proposed devices and methods are particularly suitable for implantation into the body of an animal or a human to monitor physiological conditions, such as portal and/or hepatic venous pressure, and for enabling frequent venous pressure remote polling using the resonant frequency of the implanted sensor.
