Computer Aided Drafting Solid Modeling

A SolidWorks solid modeling representation of the neonatal monitoring electrode and accelerometer assembly has been created to provide a visualization of the attachment of an accelerometer to an electrode.  The accelerometer can be easily attached to the small area afforded on top of the electrodes, which are already used in the Hershey Medical Center NICU to monitor heart rate and other vital signs.  This approach to coupling the sensor with the electrodes will not only minimize skin irritation but will also provide good adhesion for the accelerometer so that little error will be introduced by damping effects.  In the future, the sponsor hopes to produce monitoring electrodes with integrated accelerometers for mass distribution.  At this stage in development, double sided tape will provide the adhesion of the accelerometer to the electrode.  Furthermore, alignment and position on the electrode is not of great concern since the accelerometer only interprets movement in one-dimension—perpendicular to the chest and thus the electrode surface.
