Title:
POLARISATION METHOD FOR SENSITIVE ELEMENT CHIP
Document Type and Number:
WIPO Patent Application WO/2015/172587
Kind Code:
A1
Abstract:
A polarisation method for a sensitive element chip. The sensitive element chip comprises one or a plurality of pyroelectric relaxor ferroelectric single crystal sensitive elements. An upper and a lower surface of the pyroelectric relaxor ferroelectric single crystal sensitive element are respectively provided with electrodes. An upper electrode arranged on the upper surface is a single electrode, and a lower electrode arranged on the lower surface comprises a left electrode and a right electrode separated from one another. The left electrode and the right electrode are not connected to one another to form the lower electrode as a divided electrode. The left electrode is connected to a positive end of a power source, the right electrode is connected to a negative end of the power source, and the upper electrode is grounded. Via the present polarisation method, full use may be made of the advantages of distributed electrodes, dielectric loss and the dielectric constant may be reduced, and high temperature polarisation may be performed.
