Belt for use in e.g. animal for monitoring condition of animal, has optical sensor for detecting skin color, and electric resistance sensor for determining resistance of skin, where color and resistance change depending on blood flow

摘要

The belt has an acoustic sensor for detecting noise of an animal and attached at a side that is turned towards the animal, and a pressure sensor for detecting pressure in all sides of the animal, where the pressure sensor is attached at an inner side or outer side of the belt. A thermo sensor detects temperature of the animal, and an optical sensor detects skin color of the animal. An electric resistance sensor determines resistance of the skin, where the skin color and the resistance change depending on blood flow of the animal.
