Abstract: The present disclosure relates to an electronic tag for behavioural monitoring of animals, the electronic tag comprising a microprocessor and at least one sensor. The electronic tag is configured to obtain, via the at least one sensor, movement data of an animal to which the electronic tag is attached and to determine, based on the obtained movement data, a behaviour of the animal. The disclosure further encompasses a corresponding method as well as an ear tag.

Abstract: The present invention relates to a device for recording and storing of measurement data related to an object or living subject. The device comprises at least one sensor configured to measure data related to the object or living subject, a memory, and a controller configured to store the measured data in the memory. At least one photosensitive element is configured to convert electromagnetic radiation into electrical current. A transceiver is configured to transmit the measured and/or stored data and to receive data signals. At least one capacitor is configured to store electrical current from the at least one photosensitive element. The controller is configured to measure the voltage of the at least one capacitor.
