Abstract

The biotelemetry device (100) comprises a microcontroller (101) for generating an electrical setpoint signal (CS); a radio antenna (103) for transmitting an electromagnetic wave (EMS) by converting anincident electrical signal (IS); a radiofrequency circuit (102), interconnected between the microcontroller (101) and the radio antenna (103). The radio antenna (103) is configured such that, when the biotelemetry device (100) is placed in the biological medium (110), it can be impedance-mismatched relative to the radiofrequency circuit (102) so as to generate a reflected electrical signal (RS) by reflecting a fraction of the incident electrical signal at the same time that the radio antenna is transmitting the electromagnetic wave (EMS).

Description

technical field [0001] This specification relates to biotelemetry devices intended for use in in vivo media, and related methods. Background technique [0002] In the biomedical field, biotelemetry devices are used to acquire physiological signals and analyze the associated physiological data. [0003] Among biotelemetry devices, there are ingestible and / or implantable wireless biotelemetry devices that can be used both to collect and transmit physiological signals and to achieve therapeutic functions such as drug delivery or electrical stimulation. These biotelemetry devices are for example in the form of ingestible capsules or implants which can be inserted in the body of a human or animal. [0004] A. Kiourti et al. published a paper entitled "Implantable and ingestible medical devices with wireless telemetry functionalities: a review of current status and challenges" in the journal "Bioelectromagnetics" in 2014 (implantable and ingestible medical devices with wireless t...
