Domestic Focus
OPINION: After hogging the media limelight for telling a NZ Chinese MP to "go back home", Winston Peters has decided to focus on a domestic issue - oil and gas drilling.
Researchers from China, writing in the journal iScience, have designed a wearable smart device for cows that captures the kinetic energy created by their smallest movements. The technology is housed in a scallop-shaped shell, which is attached to a cow’s ankle or neck.
An electromagnetic generator converts kinetic energy into electrical energy, which is storied in a lithium battery that powers the wireless monitors.
Information can then be gathered, including the amount of exercise the animal gets, reproductive cycles, disease, oxygen concentration, air temperature, humidity and milk production, helping ensure good health and improving breeding productivity.
