Nano-generator output performance test method based on performance test system

Abstract

The invention provides a nanometer generator output performance test method based on a performance test system. The performance test system comprises a tubular linear motor, a friction nanometer generator, a high-resistance electrometer, a microprocessor and a display module. According to the nanogenerator output performance test method, a high-resistance electrometer is matched with a microprocessor to realize synchronous analog-digital signal conversion of current, voltage or charge analog signals to be tested; and meanwhile, a high-speed digital signal acquisition unit arranged in the microprocessor is used for quickly collecting output digital signals in a lossless manner. In this way, noise characteristic frequencies are screened out by combining spectrum characteristics of background noise and test data, and a filter is constructed on the basis of the noise characteristic frequencies to carry out post-processing on the collected signals, so that high-frequency and background noise interference is filtered out. According to the method, lossless and accurate measurement of the output signal of the friction nanometer generator is realized.
