Nowadays, wireless sensor devices have received wide attention across medical application
areas; among them, implantable sensing devices are between the most important
because of the contribution they make to healthcare and investigations. Nevertheless,
the implantable sensing devices must be tested before pre-clinical or in-vivo studies
are initiated and test benches are used to perform this previous tests. For this reason,
this thesis presents the design and implementation of a test bench to acquire the data
from an implantable sensing device that is being developed and will be used to sense
the pressure within the thoracic cavity of mammals. The test bench consists on: a
sealed container with two connections to increase and sense the internal pressure and
is the environment where the sensor will be tested, and a wireless communication system
that will acquire and process the sensor’s signal and is consisted of two principal
modules that will communicate between them via radio frequency at the biomedical
admitted band of 433 MHz using an implemented communication protocol. Finally,
the calibration and tests on a pizoresistive pressure sensor have been performed to
prove the functionality of the system and the experiments results are presented.
