Telemetry - used to monitor temperature, gross motor activity and heart rate data.
Physiological and behavioral monitoring oftransgenic mice and other laboratory animals has never been simpler. Through the use of biotelemetry and a variety of available sensors, it is possible for VitalView to monitor up to seven different physiological or behavioral parameters from a single laboratory subject
Combinations of the following parameters may be monitored for multiple laboratory subjects using VitalView:
Body Core Temperature
Heart Rate
Gross Motor Activity
Running Wheel Turns
Drinking/Licking Frequency
Feeding Behavior
Ambient Temperature
Ambient Light
E-Mitter Battery-Free Implantable Transponders:
Using telemetry to provide temperature, gross motor activity and heart rate data. An E-Mitter is a small implantable transponder that is powered by capturing energy from electrical fields generated by the ER-4000 Energizer/Receiver. This allows the E-Mitter to operate without batteries and remain implanted indefinitely to monitor the subject''s temperature, activity or heart rate. As a result, high costs and downtime of explantation, refurbishment and reimplantation are avoided.
