  • Passive pyroelectric infrared sensor with sensor elements on a single crystal
    Patent number: 12699007
    Abstract: Described herein are techniques for reducing spike noise arising in pyroelectric infrared sensors due to charge build up. The sensors developed by the inventors and described herein rely on the use of dummy elements positioned to prevent or limit charge build-up in the unused space. A first sensing element comprises a first portion of the first layer of conductive material, a first portion of the layer of pyroelectric material, a first portion of the second layer of conductive material and a first absorption region coupled to the first portion of the first layer of conductive material. A dummy element comprises a second portion of the first layer of conductive material, a second portion of the layer of pyroelectric material and a second portion of the second layer of conductive material. The first layer of conductive material defines a first gap between the first portion of the first layer of conductive material and the second portion of the first layer of conductive material.
