General Questions
Is the solution available for mice?
Not yet. ETISENSE team is developing the future solution adapted for mice. The demand is growing for a non-invasive solution available to firstly record a high-quality ECG on freely-moving mice. Follow Etisense to know more.
Should animals be sheared before each measurement?
In rats, the quality of ECG signal depends largely on the condition of the skin where the electrodes are applied. The need for shearing will depend on the study design. For a single measurement lasting a few hours, shearing 2 to 3 days prior to the session is usually sufficient. For repeated measurements over several days, or longitudinal measures, it will likely be to shear again to maintain good signal quality.
In dogs, shaving is not required to obtain high-quality ECG signals, thanks to the 3D-printed ECG patches directly embedded in the jacket.
How many animals can be monitored simultaneously with DECRO solution?
DECRO solutions can be configured to monitor from a single animal up to 16 animals simultaneously, depending on the study requirements. Systems designed for 4 or more animals can be easily expanded to accommodate additional emitters and monitor more animals as needed.
On Our Jackets
How to manage the choice of an incorrect jacket size?
Etisense jackets are individually packaged in sealed bags, each with a unique number and size. If the jacket has not been opened, it can be exchanged upon request by contacting ETISENSE.
How can I restock my jackets?
Jackets are only produced by ETISENSE and distributed either by ETISENSE or its designated distributors. You can ask your commercial contact or place an inquiry on ETISENSE contact page.
Can we wash rat jackets before reuse?
Although the jackets are equipped with biosensors, they are considered accessories and are intended for single use per animal per study — following the principle of 1 jacket – 1 rat – 1 study. They are not designed to be washed and reused across different animals or studies.
About Our Hardware and Software
Are the batteries rechargeable?
Yes, they are. The emitter is provided with USB rechargeable and replaceable batteries. They are reusable without repackaging. A full charge is intended to last around 2.30 hours.
What is the maximum distance between the animals and the acquisition unit?
Both the animals and the acquisition unit should be located in the same room. The signal range can reach up to 10 meters, provided there are minimal obstacles such as metal cages or thick walls, which can interfere with signal transmission.
Is the LASA Software GLP-compliant?
Yes, our solution can be made GLP-compliant through the addition of two optional modules to the base software:
- Audit Trail Module: Enables full traceability by implementing an audit trail for both the system and individual studies.
- User Authentication and Permission Module: Provides user authentication and role-based permission management.
These modules ensure the system meets the requirements for Good Laboratory Practice (GLP) compliance.
