rodentPACK, backpack system for rat

rodentPACK is a telemetry system to investigate biopotentials (ECG, EEG, EMG) and acceleration on freely moving animals 50g and upwards, such as rats.

It may be fixed to the cranium for neuro cardiovascular studies, or worn in a jacket for non-invasive ECG recordings. The wireless backpack configuration allows non-invasive recording of:

  • 1 or 2-lead ECG (2, 3 or 4 electrode cables)
  • x/y/z and global acceleration for postural and activity assessment



No surgery


Quick setup


Cost effective


System Configuration

rodentPACK miniature transmitter (5.2g) is worn in a jacket and fitted with miniature ECG cables and skin electrodes.

Digital telemetry receivers are positioned in the animals’ room, within 3 to 5 meters distance from their associated transmitters.

Each subject is therefore free to move, single or group-housed in its cage, during the acquisition (up to 32 rats in the same room with no required shielding).

The whole system is compact, as a single receiver can communicate with up to 4 transmitters. Receivers are powered and transmit data through a single Ethernet cable.

With rodentPACK system, we offer a cost-effective system with:

  • 150 hours of continuous recording with same batteries
  • No refurbishment (batteries cost less than $2/recording)
