Claim 14:
15. Biotelemetry measurement method, the method being intended to be implemented by means of a biotelemetry device placed in a surrounding biological medium, the method comprising:
a generation of an electrical setpoint signal by a microcontroller of the biotelemetry device;
an emission, by a radio antenna of the biotelemetry device, of an electromagnetic wave to an external device by conversion of an incident electric signal;
a generation of a reflected electrical signal, the reflected electrical signal resulting from an impedance mismatch of the radio antenna with respect to a radio frequency circuit when the biotelemetry device is placed in the biological medium and being generated by reflection by the radio antenna of a fraction of the incident electric signal concomitantly with the emission of the electromagnetic wave, wherein the radio frequency circuit is interconnected between the microcontroller and the radio antenna;
a picking up, by the radio frequency circuit of the biotelemetry device of a first fraction of the electrical setpoint signal and of the electrical signal reflected by the radio antenna;
a transmission to the radio antenna of a second fraction of the setpoint electrical signal, wherein the second fraction of the setpoint electrical signal forms the incident electric signal;
a determination, by the microcontroller, of a reflection coefficient based on the first fraction of the electrical setpoint signal and the reflected electrical signal.
