Embodiment Construction

[0037] Such as figure 1 As shown, the flexible piezoelectric film sensor performance testing tool provided by the present invention includes a base 1 on which a power module 2 and an oscilloscope 3 are movably connected. In a specific embodiment, the power module can use a 220V to 12V 3W isolated and stabilized voltage AP12N03-ZeroAC-DC switching power supply module, and can also use No. 5, No. 7 dry batteries or lithium-ion batteries to form a working voltage of 3-12V required by the geared motor. , to provide working power for the geared motor. The oscilloscope can use the UPO2102CS dual-channel oscilloscope of Unilever Technology (China) Co., Ltd. When the oscilloscope is used, it is connected to an external 220V AC, and the positive and negative poles of the oscilloscope and the two poles of the flexible piezoelectric film sensor to be tested (regardless of positive and negative) connect. Specifically, when the geared motor drives the blades to rotate, the voltage signal...

Abstract

The invention discloses a flexible piezoelectric film sensor performance testing tool and a testing method thereof, relates to the technical field of sensor performance testing, and particularly belongs to the flexible piezoelectric film sensor performance testing tool and the testing method thereof. The device comprises a base (1), a power module (2) and an oscilloscope (3) are movably connectedto the base, the power module is connected with a gear motor (7), the oscilloscope is connected with a to-be-tested flexible piezoelectric film sensor (13), a first supporting rod (4) and a second supporting rod (5) are arranged on the base, and a motor supporting platform (6) is installed on the first supporting rod and fixedly provided with the gear motor (7). The output end of the speed reducing motor is connected with blades (10); and a sensor clamping piece platform is mounted on the second supporting rod. The flexible piezoelectric film sensor has the advantages of being simple in structure, high in practicability and capable of measuring the sensitivity, the normal-temperature service life (fatigue test) and the high-low-temperature service life of the flexible piezoelectric film sensor at the same time.

Description

technical field [0001] The invention relates to the technical field of sensor performance testing, in particular to a flexible piezoelectric film sensor performance testing tool and a testing method thereof. Background technique [0002] Flexible piezoelectric film is a functional material that can realize the mutual conversion of electrical signals and force signals, mainly polyvinylidene fluoride piezoelectric film and polypropylene piezoelectric electret. Piezoelectric strain constant is an important parameter reflecting the properties of piezoelectric materials. The piezoelectric strain constant reflects the change of charge in the direction of the material caused by the piezoelectric material being stressed in a certain direction. When the flexible piezoelectric film material is made into a flexible piezoelectric film sensor, the piezoelectric strain constant will change due to packaging and other reasons, and then using the piezoelectric strain constant to reflect the...
