    Area of Science:

    • Veterinary Physiology
    • Biomedical Engineering
    • Animal Reproduction

    Background:

    • Long-term physiological monitoring in wild animals like badgers and foxes is crucial for understanding reproductive cycles and uterine activity.
    • Commercial physiological transmitters have limitations for extended studies, including short battery life (≤15 days) and large dimensions unsuitable for implantation.
    • Current technology restricts continuous uterine muscular activity recording in small wild mammals.

    Purpose of the Study:

    • To develop and assess a novel miniature implantable receiver module for controlling physiological transmitters.
    • To enable intermittent activation of transmitters for recording uterine muscular activity in badgers and foxes.
    • To overcome the limitations of commercial transmitters for long-term, intermittent physiological data acquisition.

    Main Methods:

    • Conception and construction of a miniature implantable receiver module.
    • Integration of the receiver module with a physiological transmitter for remote activation/deactivation.
    • Testing the system's feasibility for recording uterine muscular activity in target species (badger, fox).

    Main Results:

    • A miniature implantable receiver module was successfully designed and constructed.
    • The module allows for the intermittent operation of physiological transmitters, extending their effective use.
    • This system addresses the need for controlled, short-duration recordings, which are sufficient for assessing uterine activity evolution.

    Conclusions:

    • The developed miniature implantable receiver module is a viable solution for long-term physiological monitoring in wild animals.
    • This technology overcomes the battery life and size constraints of commercial transmitters.
    • The system facilitates efficient and targeted data collection for uterine activity studies in species like badgers and foxes.
