AIR VARIABLE CAPACITOR COMPRISING AN INTERDIGITAL MOBILE COMB AND FIXED COMB, ACCELEROMETER AND GYROMETER COMPRISING SUCH A CAPACITOR
First Claim
1. A capacitor with variable air-gap, the capacitor comprising a mobile comb and a fixed comb, each of the combs comprising a body and a plurality of teeth, each having an end fixed to the body and a free end, the teeth of the mobile and fixed combs being interdigital, an air-gap of said capacitor being adjustable by a transverse movement of the teeth of the mobile comb, wherein the teeth of the mobile comb have geometric differences between one another, in order to attenuate the transverse resonance modes of the mobile comb.

Abstract
The invention relates to an air variable capacitor including a mobile comb and a fixed comb. Each of the combs include a body and teeth each having an end fixed to the body and free end. The teeth of the mobile and fixed combs being interdigital and an the air-gap of the capacitor is adjustable by the transverse movement of the teeth of the mobile comb. The teeth of the mobile comb have geometric differences between one another, in order to attenuate the transverse resonance modes of the mobile comb.
