• receiving, by a wireless data receiver of a monitoring system, wireless data signals from each capsule of one or more capsules of the monitoring system, the one or more capsules being each arranged in a cavity of a respective device of the one or more devices;
• and
• digitally processing, by at least one processing unit of the monitoring system, the wireless data signals to determine the wear degree of the device having arranged therein the respective capsule associated with the wireless data signals;
• wherein each capsule of the one or more capsules comprises:
• walls enclosing an inner chamber configured for housing an electronic device, and
• a slot antenna arranged in at least one of the walls,
