Telemetry

Radiotelemetric transmitters enable the continuous collection of physiological data in conscious freely moving animals, e.g. pressure or biopotential signals, respiration rate, body temperature or activity.
 

For the use in small rodents miniaturized transmitters are available. The transmitters can be placed either subcutaneously or intraperitoneally so that all attached catheters and leads are completely internalized - thus eliminating the risk of wound infection.

The corresponding data acquisition system enables the contact-free monitoring of animals moving freely within their cages. The implanted transmitter transmits the digitized data via radio frequency signals to a nearby receiver plate. Animals can be (group) housed in their home cage - handling is minimized thus avoiding stress related artefacts. Instrumented animals can serve as their own controls.
