本文介绍一种用于设计电容驻极体换能器的新原理。与以前介绍的系统相反,在运动元件(驻极体或电极)与背极之间不需要有空气间隙。它是利用系统产生非均匀变形时,驻极体内所嵌入的电荷对电容器电极所产生的相对位移。这种非均匀变形是通过具有不同张力模量的介质组成的重叠层而获得。我们首先阐述这种换能器的一般原理和初步得到的灵敏度。 This article describes a new principle for designing capacitor electret transducers. In contrast to the system previously described, there is no need for an air gap between the moving element (electret or electrode) and the back electrode. It is the use of the system to produce non-uniform deformation, the electret embedded in the charge on the capacitor electrode relative displacement. This non-uniform deformation is obtained by overlapping layers of media having different tensional moduli. We first describe the general principle of this transducer and the initial sensitivity obtained.
