Technology is fast-growing in the field of wearable healthcare devices to provide ease and comfort to humankind. Sensors play a vital role in designing any wearable devices. Wearable devices for diabetes is an emerging field. Research shows various trends from using the first generation glucose sensors to continuous glucose monitoring. Different sensors measure glucose from the blood, dermi-layer of the skin, sweat and/or saliva. Several studies show a relation between blood glucose and salivary glucose or blood glucose and Interstitial fluid glucose which discloses a path to replace the traditional finger prick test to non-invasive glucose measurement devices. Along with this, technology is having a paradigm shift towards continuous glucose monitoring. Continuous glucose monitoring is challenging as it holds expectations to provide real time accurate data with lesser calibration and respective sensors that are only sensitive to glucose. A wearable device with biocompatible sensor and reliable performance is the expectation of the healthcare device. Our analysis shares different amperometric sensors from a range of invasive to non-invasive glucose monitoring with the help of electrochemical/bioimpedance methodology. The objective is to study the state-of-art sensors which will be helpful in designing a wearable and continuous glucose monitoring device specially for people suffering from Diabetes mellitus type 2.
