Description

Novel wearable sensor structure Technical Field The application relates to the technical field of sensors, in particular to a novel wearable sensor structure. Background With the development of sensor technology, in particular the popularity of wearable devices, it has become possible to use acceleration sensors to automate and refine animal behavior monitoring. An accelerometer is a device capable of measuring acceleration and is generally used to detect the state of motion of an object. Such sensors are typically mounted on the neck, legs or other body parts of the animal to aid in the overall capture of the animal's movement information. By monitoring the movement patterns of the livestock, farmers and veterinarians can detect abnormal behaviour more timely, thereby taking appropriate measures, reducing disease transmission and improving farming efficiency. These challenges are particularly pronounced based on the problems of poor waterproof performance and poor protection of internal circuitry of existing sensors, particularly in those with USB interfaces. Although the data in the sensor memory can be conveniently downloaded to the computer through the external USB port, the protection performance of the sensor structure, particularly the waterproof performance, is greatly reduced.
