Recently, people have also suggested developing transmitters which will degrade and disappear within a short time, which would eliminate the need for animals to be forced to carry on wearing transmitters for the rest of their lives after the research has finished, like wedding rings.
近來更有人建議應該發明一種在短時間內可以自動毀滅、消失的發報器，如此就不須在研究結束後，動物還得被強迫終身帶著像結婚戒指一樣的發報器。
