Vehicle acceleration measurement capacitive detector having substrate with anchorage/moving electrodes and spring/absorption mechanism limiting spring effort needed during measurements

摘要

The acceleration measurement capacitive detector has a substrate on an earth plane (11) with a first anchorage (14) of a moving unit. There are moving electrodes (10a,10b) above the substrate. There are fixed electrodes (17a,17b) facing the moving electrode. A spring (12) is placed between the moving unit together with a constraint absorption element (13), reducing the required spring effort.
