Title
(EN) Resonant tag with a conductive composition closing an electrical circuit
(ZH) 带有闭合一个电路的一种导电成分的谐振标签
Abstract
(EN)
Briefly stated a tag (10) includes a dielectric substrate having first and second opposite principal surfaces. An electrical circuit having an electrically conductive pattern (18) is formed on at least one of the principal surfaces of the dielectric substrate, the conductive pattern including a gap (22) which establishes an electrical open circuit. An electrically conductive composition (24) including electro-conductive particles (24) is provided for bridging the gap in the conductive pattern to temporarily establish an electrical closed circuit which resonates when exposed to electromagnetic energy at a frequency within a predetermined frequency.

(ZH)

概括的说,一种标签(10)包括一个带有第一和第二相对主表面的介电基片。一个具有导电图案(18)的电路形成在介电基片的主表面的至少一个上,该导电图案包括一个建立电气开路的间隙(22)。提供一种包括导电颗粒(24)的导电成分(24),用来桥接在导图案中的间隙,以便临时建立一个电器闭合电路,该电路使谐振电路当暴露于在一个预定频率范围内一个频率下的电磁能量时谐振,其中把标签暴露于一个机械力持续一个预定时间,使该成分的至少一部分部分地消散,导致在电路中的一种电气开路状态,这防止电路在预定频率范围内谐振。
