DEVICE, SYSTEM AND METHOD MEASURING PIEZOELECTRIC PROPERTIES OF THE PIEZOELECTRICITY NANOMATERIALS

摘要

Disclosed are a device, a system, and a method for measuring piezoelectric properties of a piezoelectric nanomaterial. The device for measuring the piezoelectric properties of the piezoelectric nanomaterial comprises: a nanopowder press unit; an indenter position controlling unit; a press weight controlling unit; and an electronic signal measuring unit. The nanopowder press unit includes: a transparent electron microscope specimen holder which includes a conductive indenter; and a powder supporter in which piezoelectric nanopowder is distributed which is faced to the conductive indenter. The indenter position controlling unit applies voltage to a piezoelectric nanotube included the specimen holder and controls the position of an indenter. The press weight controlling unit is included in the specimen holder; and controls piezoelectric weight which is applied to the piezoelectric nanopowder by using a weight converting device connected to the indenter and the piezoelectric nanotube. The electronic signal measuring unit measures an electronic signal generated in the piezoelectric nanopowder in real time by using a measuring device which is electrically connected to the powder supporter and the conductive indenter.
