The FreeStyle Libre Sensor should not be exposed to common electrostatic (ESD) and electromagnetic interference (EMI), including airport metal detectors. Therefore, it is necessary to remove the Sensor before going through a full-body scanner.
The reason for this is that the FreeStyle Libre Sensor is a delicate electronic device that can be affected by ESD and EMI. These types of interference can disrupt the functioning of the Sensor, potentially leading to inaccurate readings or even damage to the device itself.
To ensure the proper functioning of the Sensor and to avoid any potential issues, it is recommended to remove it before going through a full-body scanner. This is a precautionary measure to protect the integrity and accuracy of the device.
However, it is important to note that you can keep the FreeStyle Libre Reader on while going through the scanner. The Reader is designed to be more resilient to ESD and EMI, and it should not be affected by the metal detector or other airport security equipment.
In my personal experience, I have always removed the FreeStyle Libre Sensor before going through metal detectors at airports. I have found it to be a simple and quick process, and it gives me peace of mind knowing that I am taking care of the device properly.
In summary, to ensure the proper functioning of the FreeStyle Libre Sensor and to avoid any potential issues, it is recommended to remove the Sensor before going through a full-body scanner or any other equipment that may generate electrostatic or electromagnetic interference. The Reader, on the other hand, can be kept on while going through these security measures.
