Novel material physical piezoelectric experiment device

Abstract

The invention discloses a novel material physical piezoelectric experiment device, belonging to the technical field of physical experiments. The novel material physical piezoelectric experiment devicecomprises a base, wherein upright posts are respectively arranged on the left side and the right side of the top of the base; a cross beam is arranged at the top between the two groups of upright posts; a bearing block is arranged at the central position of the bottom of the cross beam; a threaded sleeve is inserted into the bottom of an inner cavity of the bearing block; a threaded column is screwed to the inner cavity of the threaded sleeve; a pressed block is arranged at the bottom of the threaded column; a pressure sensor is embedded in the central position of the bottom of the pressed block; a voltage detecting device, a U-shaped groove with an upward opening and an experiment host are sequentially arranged at the top of the base from left to right; a display screen is embedded intothe surface of the experiment host; the relationship between the applied pressure and voltage generated by a piezoelectric material can be visually displayed; in addition, a display effect is vivid and the teaching efficiency is improved. The device is simple in structure, is convenient for teaching of teachers and operation of students and meets use demands.

Description

technical field [0001] The invention relates to the technical field of physical experiments, in particular to a novel piezoelectric experimental device for material physics. Background technique [0002] The characteristic direction of materials physics is in the fields of semiconductor physics, electronic materials, microelectronic devices, etc., such as CPU. The requirements for students' mathematical and physical foundation are relatively high, and the emphasis is on cultivating students' application ability and innovation ability in the development of new electronic materials and microelectronic device technology, analysis and design. Piezoelectric materials are crystalline materials that generate a voltage between their two ends when pressure is applied. Existing physical experiment devices can't show the characteristics of piezoelectric materials well, which is not easy for students to understand. To this end, we propose a novel piezoelectric experimental setup for m...
