9. A muscle movement sensor, comprising a substrate, an information capturing film layer, and an insulative packaging layer which are stacked in sequence, and a converter which is one of a single chip microcomputer and a field-programmable gate array, wherein the information capturing film layer comprises a plurality of conductive films, the converter is connected to each of the conductive films, and the converter is configured to determine a capacitance corresponding to each of the conductive films based on an electrical signal on the conductive film, and the capacitance corresponding to each of the conductive films is one of following capacitances:
a capacitance between a ground line in the information capturing film layer and one of the conductive films; and
a capacitance formed by a first conductive film, an insulative layer in the information capturing film layer and a second conductive film which are stacked on the substrate in sequence, the first conductive film and the second conductive film being two conductive films of the plurality of conductive films;
and, the converter is further configured to send capacitances corresponding to the plurality of conductive films to the processor, so that the processor is able to determine, in a case that the muscle movement sensor is fixed onto a moving part of a living body so that capacitances corresponding to conductive films adjacent to muscles of the moving part changes with changes in forces which are applied to the conductive films adjacent to the muscles and caused by deformations of the muscles, a pressure exerted on each of conductive films based on the capacitances corresponding to the plurality of conductive films.
