Abstract
Il sensore di accelerazione comprende un corpo cilindrico di materiale conduttivo; un corpo inerziale magnetizzato caricato internamente al corpo cilindrico in modo da essere mobile longitudinalmente al corpo cilindrico; un corpo conduttivo previsto su una superficie estrema di almeno una estremità del corpo inerziale magnetizzato longitudinalmente al corpo cilindrico; una coppia di elettrodi disposti ad una estremità, longitudinalmente al corpo cilindrico, e resi conduttivi attraverso il corpo conduttivo quando contattano il corpo conduttivo del corpo inerziale magnetizzato; e un corpo di attrazione in materiale magnetico disposto all'altra estremità, longitudinalmente al corpo cilindrico, e che attrae magneticamente in modo reciproco il corpo inerziale magnetizzato. Il procedimento di fabbricazione comprende le fasi di assemblare il sensore di accelerazione incorporando il corpo inerziale prima che diventi corpo inerziale magnetizzato; e magnetizzare il corpo inerziale mediante la successiva applicazione di un campo magnetico a questa unità assemblata.
