Description
Thin-film Barium Strontium Titanate (BST)-based light sensors have significant potential for application in various optical detection systems due to their excellent dielectric characteristics and photoresponsive properties. However, the development of these sensors has primarily focused on material characterization and sensing performance, while the mechanical aspect, particularly the protective casing that supports operational reliability, has received limited attention. The absence of a protective casing increases the risk of damage caused by mechanical impact, dust, humidity, and improper handling, thereby reducing the reliability and service life of the sensor. This study aims to design and fabricate a casing for a thin-film BST-based light sensor that provides mechanical protection while preserving the optical functionality of the sensing element. The casing was designed by considering the sensor dimensions, active sensing area, electrical connection pathways, ease of assembly, and unobstructed light access to the sensor surface. Subsequently, the casing was fabricated using polylactic acid (PLA) material to meet the application requirements. The fabricated casing was evaluated in terms of dimensional accuracy, ease of assembly, mechanical stability, and compatibility with the sensor system.
