Abstract:
An implantable medical device (IMD) to provide therapy delivery and/or monitoring for a patient, the IMD further comprising:a control and timing circuit implementing an IMD operating mode; a microelectromechanical switch having a fixed contact, a moveable suspension member, a ferromagnetic layer formed on the suspension member, a moveable switch contact formed on the suspension member and disposed over the fixed contact, wherein the moveable switch contact is normally in a first position and assumes a second position when a predetermined magnetic field strength is applied to the ferromagnetic layer and causes a deflection of the suspension member: a switch processing circuit producing a switch signal responsive to the assumption of the second position by the moveable switch contact; and wherein the control and timing circuit implements an IMD operating mode in response to the switch signal.
