Abstract
Provided is a flexible thin film pressure sensor applicable in a hypergravity centrifugal environment, comprising a composite thin film, two metal electrodes, and a flexible composite encapsulation layer. The composite thin film includes a polyvinylidene fluoride (PVDF) matrix and a carbon nanowire filled within the PVDF matrix. The PVDF matrix includes a lower PVDF layer and an upper PVDF layer. The two metal electrodes are respectively fixed to two surfaces of the composite thin film and overlap with each other. A region of the composite thin film located between the two metal electrodes is a polarized region. The flexible composite encapsulation layer has a double-layer structure, wherein two layers of the double-layered flexible composite encapsulation layer are disposed on the two surfaces of the composite thin film, respectively, and edge portions of the flexible composite encapsulation layer extend beyond the composite thin film and are fixed to each other.
