Abstract

Sensorkonstruksjon som gir miniatyrisering og forbedret funksjonalitet. I en beskrevet utførelsesform blir en sensor fremstilt ved å etse hull inn i motsatte ender av et sylindrisk, piezoelektrisk krystall, for derved å danne et aktivt resonatorelement mellom hullene. I en annen utførelsesform har resonatorelementet åpninger dannet derigjennom, slik at to fester forblir innrettet med en x-akse hos krystallet og fester resonatorelementet til et periferisk parti av sensoren.
