RFID plus ovulation (estrus) detection tags for dairy cows have been commercially available since the 1980's. Until about 2000, all tags, from various companies, were manufactured under license of US Patent 4,247,758 and numerous foriegn patents. The motion sensor was a mercury switch.
MEMS value was clearly stated - a MEMS accelerometer measures the cow's movement. The value is predicting ovulation by combining restlessness (as measured by the accelermoter) and the cow's body temperature.
Part of this really exists in Japan. ie they track the food in supply chain with RFID tags. so that when we go to grocery shop, we can track the "journey" of the food from farm till shop and make a decision.
I don't think Ceitec use MEMS accelerometer to monitor activity of the cow. Ceitec does not make the chips they use Xfab, as fa as I know. I think they real key is the RFID tag. Sure, it's great to use MEMS but I am not sure what the benefit of MEMS here realy is or is this just a novelty in experimental stage?.
How about each steak gets an electronic signature on what the cow did in her lifetime...in top notch restaurant you will be able to preselect your cow based on MEMs sensor gather data, there will be an app for that of course...talk about value added food! (tongue firmly in cheek) ;-)
