Lithium niobate – Based sensors: A review

This paper shows lithium niobate-based sensors as an overview for different sensing applications that based on pure and doped lithium niobate film. The earlier published works are summarized as well as the lithium niobate film as sensor has found broad field as a result of increasing demand for sensing applications in different fields as healthcare, defense, security, automotive, aerospace, environment, food quality control, chemistry, medicine, biotechnologies and aeronautic. Lithium niobate film-based sensor are considered to be promising to open a new generation field to their virtues such as large dynamic range, low cost, high sensitivity, and compact size. Where, the high sensitivity was obtained among electric field sensors. While the high precision sensation value was obtained among gas sensor.
