Title:
SENSITIVE ELEMENT CHIP
Document Type and Number:
WIPO Patent Application WO/2015/172586
Kind Code:
A1
Abstract:
Provided is a sensitive element chip, comprising 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 present invention reduces dielectric loss and the capacitance of the sensitive element, the pyroelectric coefficient is higher, and the response rate and specific detectivity of a device prepared using the sensitive element chip are increased.
