Innovative Saliva-Based Glucose Sensor to Revolutionize Diabetes Monitoring::An innovative device could pave the way for more convenient diabetes monitoring. A prototype sensor that measures glucose levels in saliva could eventually offer a simple, rapid, and painless way for people to monitor their diabetes, according to the King Abdullah University of Science & Tech
Realistically cheaper monitoring would be more revolutionary than it being painless. There are already painless methods of monitoring blood sugar but the initial and ongoing costs of doing so can be a hurdle.
