Mouse Telemetry Systems
The Kaha Sciences Mouse Telemetry System enables biopotential (ECG, EEG, or EMG) recording in mice over 22 grams. This system features several unique and enhanced capabilities compared to existing technology and systems, including multiple implanted animals (up to 40) channels allowing simultaneous data recording without interference, reducing the time required for high-volume studies. Affordable single-use telemeters eliminate the need to surgically explant, clean and refurbish the implant. Analog outputs connect the Mouse Telemetry System with your preferred data acquisition system.
How Kaha Sciences Wireless Mouse Telemetry Works
The system combines digital telemetry with our patented wireless power technology. This allows power transfer from a single combined wireless power platform and digital receiver, the tBases. Key benefits of this wireless technology include:
- 24-hour sampling at a high frequency (2kHz) when the cage is on the tBase
- Recording capabilities for multiple animals simultaneously- 40 independent data collection frequencies for recording without signal interference
Advantages of Telemetry – Conscious, unrestrained, long-term
Conscious. Following surgical recovery, data is recorded from conscious animals capable of moving and engaging in normal behaviors. The ability to conduct conscious recordings also eliminates the possible influence of anesthesia on physiological signals.
Unrestrained. Animal handling and restraint can induce a stress response. Telemetry eliminates this unnecessary animal stress.
Long-term. Telemetry data recording allows researchers to record, analyze and observe the development of pathology over days, weeks or months without missing a specific data timepoint. Further, within-animal design, can enhance statistical power and reduce the number of animals required.

Get More From Your Telemetry Data
Wireless data transfer coupled to a high 2kHz sampling rate enables new research possibilities. Measurements that could once only be obtained using acute tethered experiments can be measured in telemetered, free-moving animals for weeks or months at a time.
Mouse System Configuration
The Kaha Mouse Telemetry System consists of the MT10B telemeter for biopotential recording, a tBase digital receiver and wireless power platform and a Configurator system for set up. This system can be configured to obtain biopotential data from up to 40 mice without interference between telemeters.
Mouse Telemetry System Components
Mouse Biopotential Telemeter (MT10B)
The single-use telemeter has a sampling rate of 2kHz and is delivered sterile, ready for easy subcutaneous implantation.
The tBase is used to power implanted telemeters, receive data, provide an index of animal activity and simply connects via analog outputs (BNC) to transfer data to your data acquisition system. A standard mouse cage is placed on top of the tBase and the telemeter is immediately powered.
Configurator System (TR190 and ConfigSoft)
This system controls the pairing of tBases with telemeters and works for both Kaha rat and mouse systems. Only one Configurator is required per laboratory and allows configuration and pairing of telemeters and tBases using up to 40 frequencies.
Mouse System Telemeter
The mouse telemeter is approximately 2 cm long with 8 cm bipotential leads and weighs 3.0 grams. The mouse telemeter is designed for single use and easy subcutaneous implantation and are shipped sterile ready for immediate use. The telemeter does not contain a battery and is simply powered, and therefore collecting and transmitting data, as soon as it is placed on the tBase. Each telemeter is designed to measure one biopotential signal, ECG, EEG or EMG.

Mouse System Hardware
The MT110 tBase is both a wireless power supply and receiver for Kaha Sciences mouse telemeters.
The top of the tBase has an indent (335mm (L) x 190mm (W) x 10mm (D)) which the mouse cage is placed in for the best access to the inductive power field.
The tBase generates an inductive power field which extends approximately 7cm above the surface of the indent.
When the mouse telemeter is within the tBase power field, the telemeter will be powered and data recorded.

The Configurator System (TR190 Configurator hardware and ConfigSoft software), wirelessly communicates with the mouse telemeters and tBases. The system allows the user to:
Change/configure the transmission frequency of the tBase
Change/configure the transmission frequency of the telemeter.
Run Diagnostics on telemeters and tBases.
Only a single Configurator System is required for each laboratory and it is NOT required during data acquisition. Existing Configurator hardware in use with Rat Telemetry Systems can be used with the Mouse Telemetry System, however, a firmware and ConfigSoft software upgrade may be required.
