What is telemetry?
Telemetry allows the measurement of physiological signals in freely moving animals living in their home cages without the use of tethers.
Advantages of telemetry – Conscious, unrestrained, long-term
Conscious – Anesthesia affects most physiological control systems and can significantly confound your results. Telemetry allows data to be collected from conscious animals after they have recovered from surgery and enables cognitive and behavioral studies not possible under anesthesia.
Unrestrained – Restraining animals induces stress which affects normal physiological functions and the data recorded. Telemetry allows data collection from animals in their home cage without the stress induced by the presence of researchers or handling.
Long-term – By monitoring physiological functions over days, weeks or months, researchers can study biological rhythms and follow the development of pathology as it occurs. Within animal design strengthens the statistical power of a study and can reduced group sizes.
How Kaha Sciences Wireless Telemetry Works
Kaha Sciences combines digital telemetry with our patented wireless power technology to create high-quality solutions for your physiological monitoring needs.
Kaha telemetry systems use wireless power transfer from our combined wireless power platforms and digital receivers (SmartPads for rats and tBases for mice) to provide power to our telemeters allowing 24/7, long-term, high-frequency sampling (2 kHz).
The rechargeable battery in our rat telemeters allows for data collection for 4-6 hours with the animal up to 5 metres away from the SmartPad. While on the SmartPad, the battery automatically recharges and data can be collected 24/7.
Forty independent data collection frequencies and the small footprint of our SmartPads and tBases means you can record from up to 40 animals at any one time without the need for shielding between cages to prevent interference.
