Implants for mice

easyTEL is a fully implantable telemetry system, that transmits physiological data from conscious freely moving small subjects weighing 20 g or more, single-housed.

Intended for use in preclinical research, easyTEL-S size implants are ideal for mice and offer the ability to continuously record Biopotential (ECG, EEG, EMG, EOG)* , Core Body Temperature and Activity.

*Electrocardiogram (ECG), electroencephalogram (EEG), electromyogram (EMG), electrooculogram (EOG)

Basic system

A typical setup includes:

  • Implants: to capture physiological measurements
  • Receivers: For mice, one receiver per implant is placed below the cage, to receive physiological signals wirelessly transmitted
  • A computer: equipped with IOX2 acquisition software
  • An easyMATRIX3: Linked to the computer, capable of connecting to up to 16 telemetry receivers and 8 analog inputs (Up to 4 easyMATRIX3 connect to a single computer).

easyMATRIX3 contains its own ambient pressure transducer, requiring no external ambient pressure reference monitor.


Analog signal

Up to 8 analog signals can be simultaneously acquired and synchronized with signals coming from the implant. Additional transducers are therefore added to the basic system:

  • Biopotential electrodes, for ECG, EEG, or EMG recording (signal is amplified by easyMATRIX3)
  • Strain gauge transducers (differential pressure or blood pressure transducers), powered and amplified by easyMATRIX3
  • Analog signals already amplified (connected through Lemo-BNC adapters)
