Abstract:
1. A triaxial piezoelectric sensor, comprising: a polyvinylidene (PVDF) layer having a plurality of first electrodes in an upper surface of the PVDF layer and a plurality of second electrodes in an bottom surface of the PVDF layer, each of the first electrodes and each of the second electrodes corresponding to each other and forming X-Y-Z triaxial polarized directions; a first line layer having a plurality of first electrical connection portions in a bottom surface of the first line layer and having a plurality of first signal lines in an upper surface of the first line layer, each of the first electrical connection portions and each of the first electrodes corresponding to each other; and a second line layer having a plurality of second electrical connection portions in an upper surface of the second line layer and having a plurality of second signal lines in a bottom surface of the second line layer, each of the second electrical connection portions and each of the second electrodes corresponding to each other; the PVDF layer being sandwiched between the first line layer and the second line layer, wherein when the PVDF layer deforms due to an external force; the plurality of first signal lines and the plurality of signal lines transmit an electrical signal according to the deformation of the PVDF layer.
