| Zusammenfassung: | The invention discloses a piezoelectric patch size measuring device and method. The upper end face of a measuring platform is provided with a slide testing table, an inclined included angle is formed between the slide testing table and the horizontal plane, the outer side of the end face of the slide testing table is provided with a first laser displacement sensor and a second laser displacement sensor, the first laser displacement sensor and the second laser displacement sensor are opposite to each other so as to measure the diameter size of a piezoelectric patch arranged between the two laser displacement sensors; a third laser displacement sensor is arranged above the slide testing table, and the third laser displacement sensor emits laser and irradiates the end face of the slide testing table so as to measure the thickness size of a piezoelectric patch arranged between the third laser displacement sensor and the end face of the slide testing table; and the numerical value deviation range of two or more di |
