Abstract

Un rótulo de seguridad que incluye una combinación de un circuito de frecuencia resonante con un blindaje de amplificación adyacente para intensificar la amplitud de la señal de salida. El blindaje de amplificación está ubicado adyacentemente al circuito de frecuencia resonante y está preferentemente en el mismo plano o sustancialmente en el mismo plano que el circuito de frecuencia resonante o está en un plano cercano, paralelo en general. En un ejemplo de realización, el circuito de frecuencia resonante incluye un inductor acoplado eléctricamente a un capacitor. El circuito de frecuencia resonante tiene una frecuencia central y está dispuesto para entrar en resonancia en respuesta a la exposición a energía electromagnética a o cerca de la frecuencia central, proporcionando una señal de salida que tiene una amplitud. El blindaje de amplificación está dispuesto para dirigir una porción de la energía electromagnética al circuito de frecuencia resonante para amplificar la amplitud de la señal se salida proveniente del circuito de frecuencia resonante.
