The design and implementation of a medical implantable device for bladder monitoring is presented. A network of accelerometers is to be implanted in-between the outside bladder muscle and the mucous membrane. A pressure sensor is also implanted in this submucosal layer to obtain intraluminal pressure readings. The sensor system is powered by an implanted battery and provides a wireless communication link for data and control. A smart measurement protocol allows the system to be operational for several weeks. The sensors are mounted on a flexible printed circuit board that can be elongated up to 250%, to accommodate the natural stretching of the bladder organ tissue during filling.
