The medical industry demands durable and efficient components that can work for millions of operations without degradation, in applications such as Pace-makers and Neuro-stimulators, but the same components are also used in non-critical devices such as hearing aids and pill-cams, and also in diagnostics equipments such as in scanners and X-ray machines. Highly reliable devices are required in the medical industry to ensure a long field life and ultra-miniature reed sensors perform excellently in lower power circuits. An added advantage is that they can work without drawing power for operation, which make them especially useful in battery connected devices such as in-canal hearing aids. As applications in the medical industry are cropping up quite fast, we list how reed switches and reed sensors find themselves in the most widely used areas.

Lung function tests (or pulmonary function tests, PFT) evaluate how much air a person’s lungs can hold, how quickly he or she can move air in and out of the lungs, and how well the lungs add oxygen to the blood and remove carbon dioxide from the blood… Continue reading |

The Vagus nerve in the neck is one of the primary communication lines to the brain. Vagus Nerve stimulators are implantable devices which control the stimulation of impulses to the brain. When a patient senses a seizure coming, a magnet is used over… Continue reading |

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, to cycle it through the desired modes of pacing or operation. Continue reading |

A reed sensor finds application in the tiny tip of a dentist’s drill to work as a pressure sensor, which starts or stops the drilling. When the drill is pressed against a hard surface, like teeth, it activates the drilling. Continue reading |
