Smartphone for glucose monitoring

Abstract As the treatment or cure for diabetes is yet to be developed, monitoring glucose level in blood is one of the most successful means that has proven to prolong the life expectancy of patients by enabling diabetics to manage and control their condition. Smartphones have become an inseparable part of daily life in many countries. The glucose monitoring using smartphone-based devices provides prevailing advantages including miniaturization, portability, relatively low cost, and without need of extra equipment. In this chapter, two most common techniques, that is, colorimetric and electrochemical methods, for glucose measurement were primarily discussed. The major challenges of combination with smartphone of these two methods were proposed and possible solutions for both methods were explored. Moreover, current progress of noninvasive glucose monitoring as well as the regulation and requirement was highlighted.
