According to the International Classification of Diseases - 10 (ICD-10), vision function is classified into four broad categories - normal vision, moderate vision impairment, severe vision impairment, and blindness. Visual impairment is a broad term, which involves moderate or severe vision loss or complete blindness. It is a global health concern that has a negative impact on both physical and mental health. Preventive blindness, which was considered among common ailments, will soon emerge as a major challenge to the global healthcare system. Blindness and visual impairment necessitate high costs as they not only constitute great productivity loss but also increase the burden on healthcare spending significantly. According to the International Agency for the Prevention of Blindness (IAPB), about 36 million people were categorized as blind, and about 217 million people were estimated to suffer from moderate to severe visual impairment (MVSI) in 2014. According to the World Health Organization (WHO), uncorrected errors, especially myopia, hyperopia, or astigmatism, constituted 43% of overall visual impairment cases in 2014.

Currently, the world is witnessing growing demand for low temperature co-fired ceramics, which is mainly due to the rising demand from the automotive sensors operating at harsh conditions. Also, there have been technological advancements in the electronics and computational industry. The miniaturization of electronics, followed by the demand for high computational speed, has produced harsh operating conditions for the electronic components. These conditions have consequently given rise to concerns such as heating, leading to the compromise in the performance of the gadgets. Therefore, researchers/industry professionals have had to reconsider the technological upgradations in tandem with good performance and paved way for the development of multilayer circuits or LTCC tapes. The primary factors leading to the demand for this technological innovation is increasing use of electronics in the automotive sensors, military and defense, aviation, and micro electro-mechanical sensors (MEMS), among others.
