Abstract:
1. An accelerometer of an implantable medical device having a first terminal corresponding to a first plate of a first capacitor, a second terminal corresponding to a second plate of said first capacitor and a first plate of a second capacitor, and a third terminal corresponding to a second plate of said second capacitor, the accelerometer comprising: a first substrate coupled to the first terminal of the accelerometer, said first substrate being said first plate of the first capacitor; a second substrate bonded to said first substrate, said second substrate comprising: a third substrate bonded to said second substrate, said third substrate coupled to the third terminal of the accelerometer, said third substrate being the second plate of the second capacitor, wherein the moveable mass is prevented from moving in a direction that inelastically flexes the at least one S-shaped spring.
