A NOVEL WIRELESS ESTRUS-DETECTION PROBE TECHNOLOGY FOR HEALTH-CARE APPLICATIONS OF COWS AND ITS MEMS SOLUTION

Abstract

This paper successfully presents a novel wireless probe, which consists of a micro accelerometer, temperature sensor and ring electrodes, for detecting estrus cycle of cow by in-situ measuring her posture, virginal temperature and resistance. Using the novel wireless probe, the estrus time of the cow had been successfully identified. Before the estrus, there are variations of both virginal temperature (&# 60;0.4°C) and resistance (&# 60;15%). In addition, the origins of noise signals in resistances, which are common and severe issues for similar bio-impedence measurement and low accuracy, had been successfully confirmed by using the novel probe. Therefore, in this work, a MEMS-based solution would be suggested for the estrus detection technology of high accuracy.
