A radiotelemetry transmitter for transmitting temperatures from small animals

Area of Science:

• Biomedical Engineering
• Animal Science
• Telemetry

Background:

• Accurate temperature monitoring is crucial for small laboratory animals.
• Existing telemetry devices may lack reliability or be difficult to implement.

Purpose of the Study:

• To design and test a small, reliable temperature-telemetry transmitter for laboratory animals.
• To develop a cost-effective and accessible telemetry solution.

Main Methods:

• Construction of a temperature-telemetry transmitter using standard electronic components.
• Integration of a miniature electric watch battery as the power source.
• Development of two models operating at different frequencies (100 MHz and 40 MHz).

Main Results:

• The designed transmitter provides a continuous and reliable signal.
• One model (100 MHz) is compatible with standard FM tuners for easy signal reception.
• The second model (40 MHz) offers extended battery life.

Conclusions:

• The developed temperature-telemetry transmitter is a small, reliable, and cost-effective tool for monitoring small laboratory animals.
• The dual-model approach provides flexibility in terms of signal reception and operational duration.
• This technology can enhance physiological research in animal models.
