Reed switches and Reed sensors in Pacemakers
Artificial pacemakers are implantable devices that generate electrical impulses to the heart, to contract the muscles and regulate the heart rate as required. These pacemakers need to be externally programmable for a cardiologist to select the desired rate of pacing for individual patients. In addition to this, certain models of pacemakers also allow the individual to set either a slow and fast pace for use in normal situations or during brisk walking, for example. Such mode changing in a pacemaker requires an external wand with an embedded magnet, with an extremely small reed sensor or reed switch within the pacemaker. This way the magnet in the wand actuates the reed switch within the pacemaker in the body, and cycles it through the desired modes.
