In vivo ruminant health sensor

摘要

A system and method of determining a physiological state of a ruminant animal by monitoring the pH and temperature of the animal's stomach. A battery-less, single unit sensor and transmitter is placed within the rumen or reticulum of the animal. pH and temperature measurements are taken and transmitted along with the animal identification code to a wireless receiver. The physiological state of the animal is determined using the mathematically analyzed pH and temperatures.
