Abstract:

Based on inverse piezoelectric effect of piezoceramics under the mechanic freedom and short circuit condition, bending distortion is produced when direct voltage was switched on one piece of piezoelectric bimorph which becomes shorter, and when inverse voltage is switched on the other, which is lengthened. Students can consolidate the basic knowledge and understand research thinking of material chemistry, material preparation, structure analysis and characterization. As a whole package, the course is effective in helping students complete a"visible, tangible materials and functional materials", highlight the professional application characteristics, and really appreciate the fun and knowledge application value.

Key words: Piezoelectric ceramics, Sensor, Piezoelectric effect, Laboratory teaching
