Stellar Telemetry represents the latest technology advancements in implantable physiologic monitoring. The system allows monitoring of many animals with just one receiver and facilitates group housing and social interaction. Stellar implants can be used in animal models ranging from mice to dogs and larger animals and in a wide range of research studies including phenotyping, pharmacology, behavior, metabolic, and general physiology assessment.

Stellar implants are available in two device types – memory-type implants and continuous-type implants. Both device types offer up to four physiologic channels plus temperature and accelerometer-based activity. Memory-type implants offer the unique ability to remotely record data away from the home cage without data loss thanks to implant programming and data storage. Data are transmitted whenever the implant is within range of the receiver (within approximately 5 meters). Continuous-type devices are optimized for power efficiency and can transmit continuous data for weeks to months, depending on device size, channel configuration, and user-programmed sample rate. Both device types support continuous or programmed scheduled sampling to optimize useful battery life.

The unique capabilities of Stellar implants have enabled novel research applications such as monitoring of blood pressure and ECG for sheep in free-roaming outdoor pens and monitoring of ECG/heart rate for wild seagulls over the course of several months.

The following table summarizes the features and benefits of the Stellar devices.
