Using smart technology (công nghệ thông minh) to monitor (giám sát) the health, reproductivity, location, and environmental conditions of cattle (gia súc) can help with food safety and supply chain efficiency (hiệu quả chuỗi cung ứng), but this monitoring adds energy cost to an already highly emissive industry. To combat this, researchers publishing in the journal iScience on December 1 have designed a wearable smart device for cows that captures the kinetic energy created by even their smallest movements and uses it to power smart ranch (nông trại) technology.

...The team’s smart ranch design involves cows wearing small sensory (cảm biến) devices around their ankles (mắt cá chân) and necks that are powered by everything cows do as they go about their regular ranch activities. “There is a tremendous amount of kinetic energy that can be harvested in cattle’s daily movements, such as walking, running, and even neck movement,” says co-author Yajia Pan
