Anechoic Chamber Interference Tests on a Bluetooth Low Energy Front-End Towards a Subcutaneous Glucose Sensor

Abstract

Background: The metabolic disorder which entails the absent or reduced control of blood glucose in the body by means of insulin dependence (Type 1) or intolerance (Type 2) affected more than 382 million people in 2013. Although only 13% of patients die from diabetes, there are a significant number of costly, dangerous health complications that appear if the correct control is not taken. Glucose subcutaneous Bluetooth Low-Energy sensor can help patients to constantly monitor their glucose levels and issue alarms to a cellular phone. Several tests regarding interference, robustness and coexistence were made to ensure Quality of Service in order to achieve medical diagnostic status. Materials and Methods: All measurements were performed in a full anechoic chamber with walls, ceiling and floor covered with high loss microwave absorbers. A PC USB Dongle acts as receiver for the Java developed application, where several data sets for each location were recorded.
