- This paper is the first to demonstrate passive wireless tags combined with mechanical mechanisms to achieve a sequential state based defrost detector. The antenna feed slot is influenced by a conducting plate that takes different positions according to pre-chill, freeze, defrost and refreeze conditions. The state of the tag is indicated by the read range it offers. The benefit of this approach is that no activation energy is required to change state, and the information is retained. The significance is to establish that mechanical mechanisms can retain detected events for intermittent interrogation by remote readers in the Internet of Things.
