System for in-vivo measurement of an analyte concentration

A base station for in-vivo measurement of blood glucose concentration in a human, comprising:

• a base power source to supply power to components of the base station;
• an implantable sensor for generating measurement signals that are correlated to a blood glucose concentration to be measured, the measurement signals being raw data recorded over first time intervals;
• a signal processor that executes instructions for processing the measurement signals to produce compressed measurement data for second time intervals which are at least ten-times longer than the first time intervals, the measurement data being compressed by at least a factor of ten compared to the measurement signals by selected sampling of the measurement signals and statistical processing of the measurement signals;
• base memory for storing compressed measurement data;
• and
• a transmitter for wireless transmission of the compressed measurement data.
