Abstract

"SENSOR ELETRO-MEC‰NICO PARA SENSOREAR FORçAS E VIBRAçõES". Um sensor eletro-mecânico para sensorear forças e vibrações compreende um corpo interno (1) suportado por uma estrutura de suporte piezo-elétrica (3) que por sua vez fica suspensa em um quadro envolvente (2), e terminais de sinal em lados opostamente polarizáveis da estrutura de suporte (3) . Alternativamente, o quadro envolvente (2) pode ser provido com áreas piezo-elétricas em posições suspensas no quadro (2) na estrutura de suporte. O quadro (2) pode ser adicionalmente suspenso em um segundo quadro externo (5) por um material elástico."ELECTRO-MECHANICAL SENSOR FOR SENSING FORCES AND VIBRATION". An electro-mechanical sensor for sensing forces and vibrations comprises an inner body (1) supported by a piezo-electric support structure (3) which in turn is suspended in an enclosing frame (2), and signal terminals on opposite sides. polarizable parts of the support structure (3) . Alternatively, the surrounding frame (2) can be provided with piezo-electric areas in suspended positions on the frame (2) in the support structure. The frame (2) can be additionally suspended on a second outer frame (5) by an elastic material.
